Conservation of momentum! help please!?(adsbygoogle = window.adsbygoogle || []).push({});

A m1 = 0.450 kg block is released from rest at the top of a frictionless track h1 = 2.85 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 Figure P6.47.

Figure P6.47.

(a) Determine the speeds of the two masses just after the collision.

speed of m1

m/s

speed of m2

m/s

(b) How high up the track does the 0.450 kg mass travel back after the collision?

m

(c) How far away from the bottom of the table does the 1.00 kg mass land, given that the table is 2.00 m high?

m

(d) How far away from the bottom of the table does the 0.450 kg mass eventually land?

m

Can anyone please give pointers or equations. I am so lost
