Question

if a 6-kg bowling ball is rolled down the bowling lane with a velocity of 3.5 m/s what is the momentum of the ball

Answer 1

Answer:

21 kgm/s

Explanation:

The information given from the question;

• Mass of the bowling ball = 6 kg
• Velocity of the ball = 3.5 m/s

We are required to find the momentum of the ball

• We need to know that momentum is the product of the speed of an object and its mass.

• That is, Momentum = Mass of an object × speed of the object
• This means that an object at rest has zero momentum since the velocity is also zero.

In this case;

Momentum of the ball = Mass of the ball × speed of the ball

                                     = 6 kg × 3.5 m/s

                                     = 21 kgm/s

Therefore, the momentum of the bowling ball is 21 kgm/s
