A person in a kayak starts paddling, and it accelerates from 0 to 0.63 m/s in a distance of 0.45 m. If the combined mass of the person and the kayak is 69 kg, what is the magnitude of the net force acting on the kayak?

Answer 1

V^2 = Vo^2 + 2a*d
a = (V^2-Vo^2)/2d

V = 0.63 m/s
Vo = 0
d = 0.45 m.
Solve for a.

F = M*a
M = 69 kg
Solve for F.
