A bullet of mass 10 g and velocity 800 m/s is passed through a mud wall of thickness 1m. its velocity reduces to 100 m/s . find the average resistance (work) offered by the mud wall.<br />

using
v^2 - u^2=2as
800^2-100^2=2a
(-)315000=a
we know m=0.01kg
F=ma
F=0.01*(-)315000
F=(-)3150 N
(-) sign indicates that force is resistive
Hope this will help you......... ✌
