A wagon has a mass of 100 kg an acceleration of 2m/s/s. What is the force on the wagon?

200N

Explanation:

Given parameters:

Mass of wagon  = 100kg

Acceleration  = 2m/s²

Unknown:

Force on the wagon = ?

Solution:

From Newton's second law of motion:

       Force  = mass x acceleration

Now insert the parameters and solve;

    Force  = 100 x 2 = 200N

we need to know the time interval during which the force acts. impulse of force = momentum change
