Question

A 3.5 kg object is accelerated from rest to a
speed of 44.9 m/s in 73 s.
What average force was exerted on the object
during this period of acceleration?

Answer 1

You need to first calculate the acceleration. You can use the equation v=u+at to do that since,
t=73s
u=0
v=44.9

After you get a, use the equation F=ma to calculate the force. Mass (m) is already given 3.5Kg
