Question

A bullet of mass 8g travels at a speed of 300 m/s. The bullet hits a target and stops after a time of 100 microseconds. What is the average force exerted by the target on the bullet?

Answer 1

F= -0.024N
OR
-F= 0.024N

Solution:
acceleration found in the pic below
F=ma
F= (0.008)(-0.3)
F = 0.024N
