Question

help

Answer 1

the head of the sledge hammer weighs 22N and is moving at a speed of 7.6m/s when it strikes a skate.The skate moves 0.025m in to the ground in response. assume that forty % of the hammer kinetic energy is converted to initial kinetic energy of teh skate. apply teh work-energy theorem and obtain teh average resistive force applied to teh skate by the ground

Answer 2

Can we use g = 10 for ease?

Answer 3

ok i already did that part M=2.2kg V=7.6m/s d=0.025m

Answer 4

mass of hammer = 2.2kg
KE of hammer = 0.5 m v^2
times this by 0.6 to give the energy used by the skate to do work on the floor.
Then, force = work done / distance.

Answer 5

instead of that can i use
