A bowling ball of mass 10.2 kg moves in a straight line at 3.03 m/s.
How fast must a Ping-Pong ball of mass
3.309 g move in a straight line so that the two
balls have the same momentum?
Answer in units of m/s.

v = 9341.19 [m/s]

Explanation:

Linear momentum is defined as the product of mass by Velocity. In this way by means of the following equation, we can calculate the momentum.

where:

P = momentum [kg*m/s]

m = mass = 10.2[kg]

v = velocity = 3.03 [m/s]

Now replacing, we have:

Now the ping-pong mass is 3.309 [g] or 0.003309 [kg]

We can clear the value for v from the equation above.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
