A truck of mass `2xx10^3kg` travelling at `4m//s` is brought to rest in `2s` when it strikes a wall. What force (assume constant) is exerted by the wall?

A body of mass 2kg moving with a velocity of 10m//s is brought to rest in 5 sec . Calculate the stopping force applied.

A truck of mass 2 xx 10^(4)kg travelling at 1.5m//s collindes with another truck of mass 3 xx 10^(4)kg moving with a velocity of 2.5m//s in opposite direction If the trucks couple on collision what is their velocity?

A body of mass 3 kg hits a wall at an angle of 60^(@) & returns at the same angle. The impact time was 0.2s. Calculate the force exerted on the wall:

A man of mass 40 kg is at rest between the walls as shown in the figure. If between the man and the walls is 0.8, find the normal reaction exerted by the walls on the man. (g = 10 ms^(-2) )

A block of mass 4 kg slides on a horizontal frictionless surface with a speed of 2m//s . It is brought to rest in compressing a spring in its path. If the force constant of the spring is 400 N//m , by how much the spring will be compressed

A body of mass 2 kg is moving with a velocity of 8 m/s on a smooth surface. If it is to be brought to rest in 4 s,t hen force to be applied is

A person (40 kg) is managing to be at rest between two verticle walls by pressing one wall A by hi hands and feet and the other wall B by his back figure. Assume that the friction coefficient between his body and the walls is 0.8 and that limiting friction acts at all the contacts. a. show that the person pushes the two walls with equal force. b. find the normal force exerted by either wall on the person Take g=10 m/s^2 .
