Answer:
The experimental apparatus shown in the figure above contains a pendulum consisting of a 0.66 kg ball attached
to a string of length 0.60 m. The pendulum is released from rest at an angle of 60 degrees and collides with a ball of mass 0.22 kg initially at rest at the edge of a table. The 0.22 kg ball hits the floor a distance of 1.4 m from the
edge of the table.
(a) Calculate the speed of the 0.66 kg ball just before the collision.
2.4 m/s
(b) Calculate the speed of the 0.22 kg ball immediately after the collision.
2.8/m s
(c) Calculate the speed of the 0.66 kg ball immediately after the collision.
1.5 m/s
(d) Indicate the direction of motion of the 0.66 kg ball immediately after the collision.
____ To the left __<u>X</u>__ To the right
(e) Calculate the height to which the 0.66 kg ball rises after the collision.
0.11 m
(f) Based on your data, is the collision elastic?
____ Yes __<u>X</u>__ No
