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

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
