A16.0 kg canoe moving to the left at 12.5 m/s makes an elastic head-on collision with a 14.0 kg raft moving to the right at 16.0 m/s. after the colli-
sion, the raft moves to the left at 14.4 m/s. what is the final velocity of the canoe? disregard any effects of the water.
o 14.1 m/s to the right
o 13.9 m/s to the right
14.1 ms/to the left
13.9 m/s to the left

Option A

14.1 m/s to the right

Explanation:

From equation of conservation of linear momentum

where and are masses of raft and canoes respectively, and are initial and final velocities of raft respectively, and are the initial and final velocities of canoe respectively.

Re-arranging and making the subject of the formula

Substituting the figures given

=14.1 m/s towards right
