Question

In the outer space, a constant force is applied to a 32.5 kg probe initially at rest. The probe moves a distance of 100 m in 10 s.
(a) What acceleration does this force produce?
(b) What is the magnitude of the force?

Answer 1

d = (1/2) a t^2
100 = (1/2) a (100)
so
a = 2 m/s^2

F = m a = 32.5*2 = 65 N

Answer 2

This doesn't make since could you elaborate on how you get one half
