Question
A block with mass m1
= 0.450 kg is released from rest on a frictionless track at a distance h,
= 2.55 m above the top of a table. It then collides elastically with an object
having mass m, = 0.900 kg that is initially at rest on the table, as shown in the figure below.
m2
(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
Your response differs from the correct answer by more than 100%. m/s
V2 =
m/s
(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 h,
= 1.50 m?
(d) How far away from the bottom of the table does the 0.450-kg object eventually land?
