Question

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

Answer 1

The velocity of sphere = 400 m/s

Given:                                                              

A sphere of mass 6 kg is fired from a canon of mass  600 kg.

Canon is pushed back with a velocity of  4 m/s

To find:                                                                                

The velocity of sphere.​

Concept used:

Conservation of momentum.

That is,    initial momentum = final momentum

And momentum = mass × velocity

Explanation:

consider, mass of sphere= $m_{1}$

              velocity of sphere =  $v_{1}$

              mass of canon = $m_{2}$

              velocity of canon = $v_{2}$

Initially canon on rest then initial moment of canon = 0

Final velocity of sphere is zero so final momentum of sphere = 0

 initial momentum = final momentum

                     $m_{1}$ $v_{1}$ =  $m_{2}$$v_{2}$

                     6 ×  $v_{1}$ = 600×4

                             $v_{1}$ = $\frac{600\times 4 }{6}$

                              $v_{1}$ = 400 m/s

The velocity of sphere = 400 m/s
