Question

A person in a kayak starts paddling, and it accelerates from 0 to 0.433 m/s in a distance of 0.508 m. If the combined mass of the person and the kayak is 82.2 kg, what is the magnitude of the net force acting on the kayak?

Answer 2

Explanation:

35.3 N Explanation:

U = 0, V = 0.61 m/s,

s = 0.39 m

Let a be the acceleration. Use third equation of motion

V^2 = u^2 + 2 as

0.61 x 0.61 = 0 + 2 x a x 0.39

a = 0.477 m/s^2

Force = mass x acceleration

F = 74 x 0.477

= 35.3 N
