Question

11.A sphere of mass 6 kg is fired from a canon of600 kg. If the canon is pushed back with a velocity 4 ms-l, then find out the velocity of sphere.​

Answer 1

Answer:

Use law of conservation of energy

Explanation:

m1v1 = m2v2

m1 - mass of sphere

m2 - mass of cannon

v1 - velocity of sphere

v2 - velocity of cannon

velocity of sphere = ?

6 × v1 = 600 × 4

v1 = 400 m/s
