A person in a kayak starts paddling, and it accelerates from 0 to 0.577 m/s in a distance of 0.565 m. If the combined mass of the person and the kayak is 60.6 kg, what is the magnitude of the net force acting on the kayak?

Answer 1

vf^2=vi^2+2ad

but a= force/mass
you know vi=0 vf-.577m/s,and you know d.
solve for force.

Answer 2

F=ma
we know m but don't know the a .
So lets find the a first.
V(final)^2 = V(initial)^2+2d
so a = V(final)^2/2d
a=0.295
now F=ma
F= 60.6*0.295
=17.851 N
