Question

A boy can accelerate at 1.00 m/s 2 over a short distance. If the were to take an energy pill and suddenly have the ability to accelerate at 5.6 m/s 2, then how would his new energy pill force compare to his earlier force? If the boy's earlier force was 45 N, what is the size of his energy pill force?

Answer 1

Force equals mass times acceleration\[F=ma\]So force divided by acceleration will give you his mass. \[\frac{F}{a}=m\]If the previous force was 45N and his acceleration was 1m/s^2, then his mass is 45kg, because a newton (N) is (kg x m)/s^2. Taking his mas and multiplying it by the new acceleration of 5.6m/s^2 will give you his new force.
