A block with mass m1 = 0.450 kg is released from rest on a frictionless track at a distance h1 = 2.25 m above the top of a table. It then collides elastically with an object having mass m2 = 0.900 kg that is initially at rest on the table, as shown in the figure below.

(a) Determine the velocities of the two objects just after the collision. (Assume the positive direction is to the right. Indicate the direction with the signs of your answers.)

v1 =   m/s
v2 =

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

(c) How far away from the bottom of the table does the 0.900-kg object land, given that the height of the table is h2 = 1.85 m?

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