The 0.50 kg head of a hammer has speed of 5.0 m//s just before its strikes a nail and is brought to rest. Estimate the temperature rise a 15 g nail generated by ten such hammer blows done in quick succession. Assume the nail absorbs all the heat.

A bullet of mass 15 g has a speed of 400 m/s. What is its kinetic energy ? If the bullet strikes a thick target and is brought to rest in 2 cm, calculate the average net force acting on the bullet. What happens to the kinetic energy originally in the bullet ?

A block of mass 0.50kg is moving with a speed of 2.00m//s on a smooth surface. It strikes another mass of 1 kg at rest and they move as a single body. The energy loss during the collision is

A 1.5 kg hammer moving with a velocity of 10 m/s strikes a nail for 0.005 s. The average force exerted on the nail is

The head of a hammer (m = 1.5 kg) moving at 4.5 m/s strikes a nail and bounces back with the same speed after an elastic collision lasting 0.075 s. What is the magnitude of the average force the hammer exerts on the nail?

A hammer of mass 500g strikes an iron nail with speed of 50 m/s. If the nail stops , the hammer in a short duration of 0.01s , then find the force acting on the nail by the hammer .
