According to this equation, f=ma, how much force is needed to accelerate a 70-kg runner at 5m/s2?

a.
350 m/s

b.
14 n

c.
350 n

d.
14 m/s

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
