Question

Two campers dock a canoe. One camper has a mass of 100.0 kg and moves forward at 3.0 m/s as he leaves the canoe to step onto the dock. With what speed do the canoe and other camper move if their combined mass is 175.0 kg

Answer 1

The combined speed of camper and canoe is 1.71 m/s.

Step-by-step explanation:

Given that,

Mass of camper 1, m = 100 kg

Speed of camper 1, v = 3 m/s

The combined mass of another camper and canoe is, M = 175 kg

We need to find the combined speed of camper and canoe. According to the conservation of linear momentum, the momentum of first camper is equal to linear momentum of the canoe and the second camper.

`mv=MV\\\\V=(mv)/(M)\\\\V=(100* 3)/(175)\\\\V=1.71\ m/s`

So, the combined speed of camper and canoe is 1.71 m/s.
