Question

A canon of Mass m1 = 1200 kg fires a shell of Mass m2 = 300 kg in Horizontal direction with a Velocity v2 = 400 m/s. Find the Velocity of the Canon after it is shot. *

Answer 1

Answer:

A canon of Mass m1 = 1200 kg fires a shell of Mass m2 = 300 kg in Horizontal direction with a Velocity v2 = 400 m/s.

According to the law of conservation of momentum

m1*v1 = m2*v2

So,

Velocity of the Canon after it is shot,

$1200 \times x = 300 \times 400 \\ \\ x = \frac{120000}{1200} = 100 \frac{m}{s}$
