A football punter accelerates a .55 kg football from rest to a speed of 8.0 m/s in .25 s. What constant force does the punter exert on the ball?

The constant force exerted on the ball is 17.6 N

The first is to calculate the acceleration

= velocity/time

= 8/0.25

= 32 m/s

Force= mass × acceleration

= 0.55 × 32

= 17.6 N

Hence the constant force exerted on the ball is 17.6 N

The constant force required is 17.6 N

Explanation:

Given-

Mass, m = 0.55 kg

Initial speed, u = 0

Final speed, v = 8 m/s

Time, t = 0.25 s

Force, F = ?

We know,

Force = mass X acceleration

F = 0.55 X

F = 0.55 X

F = 17.6 N

Therefore, the constant force required is 17.6 N
