Question

Q4) A small block of mass 0.500 kg is released from rest at the top of a frictionless track 2.50 m above the top of

a table. It then collides elastically with a 1.00 kg mass that is initially at rest on the table as shown in the figure

below.

a) Determine the speed of both the masses after the collision.

b) How far away from the table, distance x, does the 1.00 kg mass land?

c) How high up the track does the 0.500 kg mass travel after the collision?

d) How far away from the table does the 0.500 kg mass land?

Explanation / Answer

initial Ep = mgh = 0.5kg * 9.8m/s
