Question

Carmen and Judi dock a canoe. 77.0-kg Carmen moves forward at 4.7 m/s as she leaves the canoe to step onto the dock. At what speed and in what direction do the canoe and Judi move if their combined mass is 115 kg.

Answer 1

Answer: 3.15m/s

Explanation:

Conservation of momentum

M1V1=M2V2

77kg*4.7m/s=115kg*V2

So therefore, V2=77kg*4.7m/s/115kg

=3.15m/s
