Question

a bullet moving with a velocity of 10 metre per second is brought to rest after the wooden plank of force and thickness calculate the acceleration of the blood​

Answer 1

Answer:

initial velocity=10m/s

final velocity=0m/s

distance traveled=4cm=0.04m

using equation of motion(v^2-u^2=2as)=

0-100=2as

=-100=2*a*0.04

-100=0.08a

a=-100/8/100=-10000/8

=-1250
