**Momentum **(p) is equal to the product of **mass **(m) and the **velocity **(v). Using the equation of momentum: **p = m × v**, the value of momentum of an object can be calculated.

Let’s solve some problems based on this equation, so you’ll get a clear idea.

## Momentum Practice Problems

**Problem 1:** Calculate the momentum of a 2 kg ball rolling towards the east with the velocity of 3 m/s.

Solution:

Given data:

Momentum of a ball, p = ?

Mass of a ball, m = 5 kg

Velocity of a ball, v = 3 m/s

Using the equation of momentum,

p = m × v

p = 5 × 3

p = 15 kg m/s

Therefore, the momentum of a ball is **15 kg m/s** towards the east.

**Problem 2:** A car of mass 800 kg is moving towards the north with the velocity of 10 m/s. What is the momentum of a car?

Solution:

Given data:

Mass of a car, m = 800 kg

Velocity of a car, v = 10 m/s

Momentum of a car, p = ?

Using the equation of momentum,

p = m × v

p = 800 × 10

p = 8000 kg m/s

Therefore, the momentum of a car is **8000 kg m/s** towards the north.

**Problem 3:** What is the momentum of a 3000 kg truck running on the highway towards the west with the velocity of 8 m/s?

Solution:

Given data:

Mass of a truck, m = 3000 kg

Velocity of a truck, v = 8 m/s

Momentum of a truck, p = ?

Using the equation of momentum,

p = m × v

p = 3000 × 8

p = 24000 kg m/s

Therefore, the momentum of a truck is **24000 kg m/s** towards the west.

**Problem 4:** If a bicycle of mass 5 kg is moving with the velocity of 15 m/s towards the south, then what is the momentum of a bicycle?

Solution:

Given data:

Mass of a bicycle, m = 5 kg

Velocity of a bicycle, v = 15 m/s

Momentum of a bicycle, p = ?

Using the equation of momentum,

p = m × v

p = 5 × 15

p = 75 kg m/s

Therefore, the momentum of a bicycle is **75 kg m/s** towards the south.
