Asked by Kristi
A person in a kayak starts paddling, and it accelerates from 0 to 0.498 m/s in a distance of 0.554m. If the combined mass of the person and the kayak is 62.6, what is the magnitude of the net force acting on the kayak?

Use the formula
F = m a
to get the force in Newtons.
In this case, m is the combined mass of kayak and the person paddling.
You neglected to provide units for the combined mass. I assume it is kilograms.
For the acceleration, a, assume uniform acceleration, in which case
Vfinal = sqrt(2aX)
a = Vfinal^2/(2X)
X = 0.554 m
