After calling a wall of `3 m` heigh a mass of weight W drops himself to the ground. If his body comes to a complete stop in `0.15 s`. After his feet touch the ground, calculate the average impulsive force in the vertical direction exerted by ground on his feet.

After climbing a wall of 3 m height, a person of weight W jumps to the ground. If the body comes to a complete stop in 0.15 s . After the feet touch the ground, calculate the average impulsive force in the vertical direction exerted by ground on the feet.

A 20 gram bullet moving at 300 m/s stops after penetrating 3 cm of bone. Calculate the average force it exerts.

A 20 gram bullet moving at 300m//s stops after penetrating 3cm of bone. Calculate the average force exerted by the bullet .

A man whose mass is m kg jumps vertically into air from the sitting position in which his centre of mass is at a height h_(1) from the ground. When his feet are just about to leave the ground his centre of mass is at height h_(2) from the ground and finally centre of mass rises to h_(3) above the ground when he is at the top of the jump. what is the average upward force exerted by the ground on him?

A thief steals a treasure box of weight w. He then jumps off a wall of height h with the box on his head. The weight felt on his head before he touches the ground is

If a man of ,mass M jumps to the ground from a height h and his centre of mass moves a distance x in the time taken by him to 'hit' the ground the average force acting on him (assuming his retardation to be constant during his impact with the ground) is :
