What constant force does the punter exert on the ball?

Click For Summary
SUMMARY

The discussion centers on calculating the constant force exerted by a football punter on a 0.55 kg football accelerated to a speed of 8.0 m/s in 0.25 seconds. The correct calculation yields a force of 17.6 N, derived from the formula f = ma, where acceleration (a) is determined to be 32 m/s². The initial claim of 19.7 N was incorrect, as the proper acceleration calculation was not applied.

Could someone help me with this problem?

A football punter accelerates a 0.55kg football from rest to a speed of 8.0 m/s in 0.25s. What constant force does the punter exert on the ball?

The force I got was 19.7 N. Is this right?

How did you get that answer?
 
17.6 no?

f = ma

f = ?
m = 0.55
a = 32 -> 4*8=32

f = 0.55*32
f = 17.6N
