vaieri [72.5K]

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

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