1. An object with a mass of 2.0 kg accelerates 2.0 m/s when an unknown force is applied to it. What is the amount of the force?

2. An object with a mass of 5.0 kg accelerates 8.0 m/s? when an unknown force
As applied to it. What is the amount of the force?

3. An object with a mass of 1500 g (grams) accelerates 10.0 m/s when an
unknown force is applied to it. What is the amount of the force?

Given: 6 questions with certain values of mass and acceleration.

To find: The amount of force?

Solution:

An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

                    F = m x a = 2 x 2 = 4 N

An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

                     F = m x a = 5 x 8 = 40 N

An object with a mass of 1500 g (grams) accelerates 10.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

Now in this mass is in grams, so converting it kg, we get:

                    1500/1000 kg = 1.5 kg

                   F = m x a = 1.5 x 10 = 15 N

Explanation:

another example of kinetic energy would be,

kinetic energy   >     moving energy
