Answer:
The constant force exerted on the bullet is 1590.87 N.
Explanation:
It is given that,
Mass of the bullet, m = 8.6 g
Initial speed of the bullet, u = 0
Final speed of the bullet, v = 430.1 m/s
We need to find the force exerted on the bullet while it is traveling down the 0.5 m length of the barrel of the rifle. Let a is the acceleration of the bullet. So,





Let F is the force exerted. It is given by :


F = 1590.87 N
So, the constant force exerted on the bullet is 1590.87 N. Hence, this is the required solution.
Answer:
90 N
Explanation:
m = 60 kg
a = 1.5 m/s^2
F = m × a = 1.5 × 60 = 90 N
Period is T=1/f
T=1/60 = 16.67 milliseconds
