A person in a kayak starts paddling, and it accelerates from 0 to 0.515 m/s in a distance of 0.319 m. If the combined mass of the person and the kayak is 64.2 kg, what is the magnitude of the net force acting on the kayak?
Homework Answers
using the equation of linear motion we have
v^2 - u^2= 2aS
0.515^2 - 0 = 2*a*0.319
a = 0.4157 m/s^2
force = mass*acceleration
= ma
= 64.2 * 0.4157 = 26.68 N
