A basketball has a mass of 1 kg and is traveling 12 m/s.

What would happen to the velocity if the momentum of the basketball were cut in half?

It would be doubled.

It would be cut in half.

It would be the same.

It would be tripled.

It would be cut in half.

Explanation:

If the momentum of the ball is cut into half, the velocity will also be halved.

The momentum of a body is the amount motion a body possess.

Momentum is given as;

       momentum= m x v

Given that;

 mass  = 1kg

 velocity  = 12m/s

Now find the momentum;

            momentum  = 1 x 12 = 12kgm/s

Halving the momentum = 6kgm/s

              mass = 1kg

 Momentum  = 1 x v

       6  = 1 x v

           v  = 6m/s

We see that the velocity reduces by half

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
