Question

A sheet of mass 20g is kept floating horizontally in air by firing bullets , each of mass 5g with the same velocity,at the rate of 10 bullets per second and the bullets rebound with the same speed in opposite directions .The velocity if each bullet at the time of impact is (Take g=10m/s^2)

​

Answer 1

The velocity of the bullet is v = 5 m/s

Explanation:

Mass of sheet "m1" = 20 g

Mass of bullet "m2" = 5 g

v = 10 m/s

g = 10 ms^2

g = m1/m2 x v

10 =20/5 x 10

4 = 10+10

4 = 20

v = 5 m/s

Hence the velocity of the bullet is v = 5 m/s
