Question

A 20 gm bullet moving at 300 m/s stops after penetrating 3
cm of bone. The average force exerted by the bullet is
-x * 104 N. Find the value of x.​

Answer 1

Answer:

Explanation: Given Data

    Mass = 20gram

             =  0.002kg (Standard Unit)

Velocity = 300m/s

   Force =  Mass × Velocity

              =  0.002kg × 300m/s

              =  0.6N

ATQ

104 * x = 0.6N

        x = 0.6/104
