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
