The average force of the rifle acting on the bullet = 60 N
We are given that,
- mass of the bullet, m = 9.00 gm = 0.009 kg
- time of travel, t = 0.03 s
- speed of bullet, v = 200 m/s
The force acting on the bullet is given by the formula -
F = m*v/t
- F = 0.009 * 200 / 0.03
- F = 60 kg m/s²
- F = 60 N
