A sled of mass 10kg sits on a hill of slope 30°. A 20kg child runs up the slope with a velocity of
5m/s. He jumps onto the sled (assume a completely inelastic collision).

a.What is the initial energy of the system?
b.What is the final energy of the system?
c.Why are these values different?
d.How far along the slope does the combination of child and sled travel before momentarily coming to a stop? Assume a frictionless slope.

michele_laino · Answer

the initial energy is the kinetic energy of child, since the sled is at the rest.

anonymous · Answer

would the final energy be equal to the initial assuming that total energy is conserved.
