Class 2, Grade 3

[Top Four Seats-Fierce Competition]

Among the top eight teams in this round, teams such as 619, Zero Point, VTOP, and CHINA [6M] are all recognized by players as traditional strong teams. The teams have advantages in both strength and experience. However, the path to promotion for these strong teams was not easy, and they were even eliminated by young teams. Although the young team does not have rich competition experience, they have unlimited fighting spirit and do not have too much baggage behind them, so they can relax and enjoy the game. The miracle of NSD team's hard-fought victory over 6M from the lower bracket and advancement to the semi-finals is a testament to their fighting and fearless spirit.

Fierce competition

Focus on the game

[Dark Horse Drive-NSD]

NSD, which stood out from the Death Group-B Group, is definitely a dark horse in this WCG finals. From a 0:6 defeat in the group stage to defeating the two major national champions CHINA [6M] and VTOP Hero Pearl, and even defeating the powerful 619 in the third place match, the process of finally winning the third place was like a phoenix reborn from nirvana, challenging yourself and making breakthroughs limit. This is also the best experience of never-say-die spirit in FPS games.

NSD team

[A stable mind creates a champion]

For a team participating in the WCG competition for the first time, the championship is an almost impossible goal. But Class Two of Three Years created this miracle. Although the team lacks competition experience, their stable mentality and performance help them on their way to the championship. In the interview, they also mentioned that although we do not have the courage of young people now, we have a mature and stable heart and an adjusted mentality, which is an important foundation for dealing with any difficulties.

In the competition of class two in three years

[Leave your dream and challenge yourself]

WCG is a platform for dreams to take off. All parametric players are here to strive for their e-sports dreams, but the road to pursuing dreams is long and bumpy. A failure does not mean the end. This is a let-down. The beginning of your new understanding of yourself. So please keep your e-sports dream alive. Every player who can step onto the WCG stage is a winner. I thought the player also said after the game: I only want to represent China on the world stage, and I have no regrets!

As shown in the figure, the left end of a horizontally placed light spring is fixed. The small object P is placed at point A on a smooth horizontal table and contacts the right end of the spring without adhesion. At this time, the spring is at its original length. Now, when P is slowly pushed to point B with horizontal leftward thrust (the spring is still within the elastic limit), the work done by the thrust is WF=8J. After the thrust is removed, P slides along the tabletop to the flat trolley Q parked on a smooth horizontal surface. The upper surface of the trolley is on the same horizontal plane as the tabletop. It is known that the masses of P and Q are m=1Kg and M=4Kg respectively, and the kinetic friction coefficient between P and Q is μ=0.4. Take g=10m/s2 and find:

(1) To prevent the block P from sliding out on the cart Q, what is the minimum length of the cart?

(2) If P does not slide out on the car Q, how long does it take for P to slide relative to Q?

As shown in the figure, an uncharged car A with an insulated upper surface and a mass of mA=1kg is placed on a smooth horizontal surface. An empty car with a mass of mB=0.5kg and a charged quantity of q=1.0×10-2C is placed on its left end. Box B has an open left end. The upper surface of the trolley is parallel to the horizontal table. A light spring is placed horizontally on the table. The left end of the spring is fixed. A small uncharged insulating block C with a mass of mC=0.5kg is placed at point O on the table and contacts the right end of the spring. When the spring is at its original length, use horizontal left thrust to slowly push C to point M (the spring is still within the elastic limit). The work done by the thrust is WF = 6J. After the thrust is removed, C slides along the table to the trolley. Inside the empty box B and collides with its right wall, the collision time is very short and C and B stick together after the collision. In the right area of ​​the desktop, there is a horizontal uniform electric field directed to the left. The electric field intensity is E=1×102N/m. The electric field suddenly disappears after acting for a period of time. The car just stops and the goods just reach the right end of the car. It is known that the kinetic friction factor μ1=0.4 between block C and the tabletop, the kinetic friction factor μ2=0.1 between the empty box B and the small workshop, the distance between OM s1=5cm, the distance between point O and point N on the edge of the table s2=90cm, the block and the empty box Regardless of the volume, g is taken to be 10m/s2. beg:

(1) The speed v of block C immediately after the collision with empty box B;

(2) The length L of the trolley;

(3) The time t during which the electric field acts.

As shown in the figure, there is a car with mass M on a smooth horizontal surface. A wooden block with mass m is placed on the horizontal upper surface of the car. The kinetic friction factor between the wooden block and the small workshop is μ. When using a level with size F When the car is pulled with constant force, the car and the wooden block remain relatively stationary and accelerate to the left together. Then during the movement ()
