A football punter accelerates a 0.52 kg football
from rest to a speed of 8.6 m/s in 0.27 s. What
constant force does the punter exert on the ball?
Answer in units of N.

Answer 1

16.6 N

Step-by-step explanation:

m = 0.52 kg, v₀ = 0, v = 8.6 m/s, t = 0.27 s

a = (v - v₀)/t

F = ma = m(v - v₀)/t = 0.52 (8.6 - 0)/0.27 = 16.6 N
