A sled with a mass of 20 kg is sliding along the snow with a velocity of 5 m/s. What is the momentum of the sled? Question 7 options:

100 kg/ms

4 kg/ms

15 kg/ms

25 kg/ms

100kgms⁻¹

Explanation:

Given parameters:

Mass of the sled  = 20kg

Velocity of the sled  = 5m/s

Unknown:

Momentum of the sled = ?

Solution:

The momentum of a body is the quantity of motion such a body possesses. Due to this;

    Momentum  = mass x velocity

Now insert the parameters and solve;

      Momentum  = 20 x 5  = 100kgms⁻¹

what type of charge does it have? negative
