Calculate the speed of the 0.66 kg ball just before the collision.

Calculate the speed of the 0.22 kg ball immediately after the collision.

Calculate the speed of the 0.66 kg ball immediately after the collision.

Indicate the direction of motion of the 0.66 kg ball immediately after the collision.

To the left To the right

Calculate the height to which the 0.66 kg ball rises after the collision.

Based on your data, is the collision elastic?

Yes No

Justify your 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 __X__ 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 __X__ No

Coefficient of elasticity of less than one means an inelastic collision.
