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

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

the bal will not change its velocity.
