world-class sprinters can accelerate out of the starting blocks with an acceleration that is nearly horizontal and has magnitude 15 m/s^2. how much horizontal force f must a sprinter of mass 60 kg exert on the starting blocks to produce this acceleration?



Answer :

Qwdog

The force exerted by the sprinter who is having a mass of 60 kg and accelerating at 15 m/s² is 900 N

The acceleration of the sprinter is 15 m/s²

The mass of the sprinter is 60 kg

The force exerted by the printer can be found using the formula,

                 F = ma

where F is the force exerted by the sprinter

          m is the mass of the sprinter

          a is the acceleration of the sprinter

Let us substitute the known values in the above equation, we get        

                          F = 60 x 15

                             = 900 N

Therefore, the force exerted is 900 N
