Abowling ball of 35.2kg, generates 218 kg. m/s units of momentum. what is the velocity of the bowling ball?

Answer is: velocity of the bowling ball is 6.19 m/s.

Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.

m(ball) = 35.2 kg; mass of a bowling ball.

p(ball) = 218 kg·m/s; momentum of a ball.

v(ball) = p(ball) ÷ m(ball).

v(ball) = 218 kg·m/s ÷ 35.2 kg.

v(ball) = 6.19 m/s; velocity of a bowling ball.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
