World-class sprinters can accelerate out of the starting blocks with an acceleration that is nearly horizontal and has magnitude 15m/s^2. How much horizontal force F must a sprinter of mass 64 kg exert on the starting blocks to produce this acceleration?
given, mass of sprinter (m) = 64 kg
acceleration of sprinter ( a) = 15 m/s2
now, horizontal force F = m x a
or, F = 64 x 15 = 960 N
hence, this sprinter must exert the force of 960 N on the starting blocks .
