Question

If a 0.5kg cart is loaded with three 1.5-kg bricks, then the total mass of the loaded cart would be 5.0 kg. If it is moving with a speed of 2.0m/s, what is its momentum?

Answer 1

The momentum of the cart is:

• 
  `p = 10` kgm/s

Explanation:

Given

Given that the 0.5 kg cart is loaded with three 1.5-kg bricks.

Thus,

Total mass m = 5.0 kg

Velcity v = 2.0 m/s

To determine

Momentum m =?

The momentum of the cart can be calculated using the formula

`p = mv`

Here:

• 
  `p` is the momentum

• 
  `m` is the mass

• 
  `v` is the velocity

substituting m = 5.0, v = 2 in the equation

`p = mv`

`p = (5)(2)`

`p = 10` kgm/s

Therefore, the momentum of the cart is:

• 
  `p = 10` kgm/s
