Question

A 20 kg cart moving at 4 m/s has how much momentum?

Answer 1

Answer:

We conclude that the required momentum is 80 kgm/s.

Explanation:

Given

• Mass m = 20 kg

• Velocity v = 4 m/s

To determine

The momentum p = ?

Important Tip:

• The momentum of an object is the product of mass and velocity.

We can determine the momentum using the formula

$p = mv$

where

• p is the momentum

• m is the mass

• v is the velocity

now substituting m = 20 and v = 4 using the equation

$p = mv$

$p = (20) (4)$

$p = 80$ kg m/s

Therefore, we conclude that the required momentum is 80 kgm/s.
