a person in a kayak starts paddling, and it accelerates from 0 to 0.36 m/sec in a distance of 0.8m if the combined mass of the person and the kayak is 80 kg,what is the magnitude of net force acting on the kayak...??

Answer 1

average velocity is ... (.36 + 0) / 2

t = d / v = .8 m / .18 m/s

acceleration ... a = .36 m/s / t

f = 80 kg * a
