Question

7. Two campers dock a canoe. One camper steps onto the dock. This camper has a mass of 80 kg and moves forward at 4.0 m/s. With what speed and direction do the canoe and the other camper move if their combined mass is 110 kg?​

Answer 1

v = 2.9 m/s

Step-by-step explanation:

m1 = 80 kg v1 = 4 m/s m2 = 30 kg m(f) = 110 kg

m1v1+m2v2/(m1+m2)=vf

(80 * 4) + (30 * 0) / (110) = v

v = 2.9 m/s

hope this helps!! :)
