Question

A cannon of mass 12000 kgs on smooth platform fires a shell of mass 300 kg in horizontally direction with a velocity 400 metres per second find the velocity of the c a n n o n after it is s h o t​

Answer 1

Answer:

10m/s

Explanation:

Mass1 =12000kg

Mass2 = 300kg

Velocity= 400m/s

Initial momentum = Final momentum

0 = m1v1 - m2v2

m1v1 = m2v2

v1 = m2v2/ m1

v1 = 300 x 400 /12000

v1 = 10 m/s

HENCE, THE VELOCITY IS 10m/s
