Question

World class sprinters can accelerate out of the starting blocks with an acceleration that is nearly horizontal and has a magnitude 15 m/s^2. How much horizontal force F must a sprinter of mass 62 kg exert on the starting blocks to produce this acceleration?

Express your answer in newtons using two significant figures.

Answer 1

F = ma = (62 kg)(15 m/s²) =

multiply then round to 2 significant figures.
