A force F hits a block of mass m=35g initially at rest.The duration of the impact is 5ms .If the force varies with time as shown in figure the speed of the block immediately after impact is

A force F is applied to the initially, stationary cart. The variation of force with time is shown in the figure. The speed of cart at t = 5 s is

Power of a force acting on a block varies with time t as shown in figure. Then, angle between force acting on the block and its velocity is

A block of mass m is at rest under the action of force F against a wall as shown in figure. Which of the following statement is incorrect?

Power due to a force actoing on a block varies with time t as shown in figure. Then angle between force acting on the block and its velocity is :-

A block of mass 2 kg is free to move along the x -axis. It at rest and from t = 0 onwards it is subjected to a time-dependent force F(t) in the x direction. The force F(t) varies with t as shown in the figure. The kinetic energy of the block after 4.5 seconds is

A 20 kg block is originally at rest on a horizontal surface for which the coefficient of friction is 0.6 . A horizontal force F is applied such that it varies with time as shown in the figure (a) & (b). If the speed of the block after 10 s is 8v then find v . ( Take g=10m//s^(2) )

A body of 2kg has an initial speed 5ms^(-1) . A force acts on it for some time in the direction of motion. The force time graph is shown in figure. The force time graph is shown in figure. The final speed of the body is

A block of mass 2 kg is free to move along the x-axis it is at rset and from t=0 onwards it is subjected to a time dependent force F(t) in the x-direction The force F(t) varies with t as shown in the figure The kinetic energy of the block after 4.5 seconds, is:
