Question

Bullet of 10g strikes a sand bag at speed of 1000m/s and get stopped after travelling 5cm.a)calculate force exertedby sand on bullet *

Answer 1

Answer:

100000 N

Explanation:

v^2-u^2 = 2as

-(1000)^2 = 2a(5/100)

-1000000 = a/10

a = -10000000 m/sec^2

F=ma

= (10/1000)(-10000000)

= -100000 N

the sand bag exerts 100000 N on bullet.
