Newton's Law of Motions

Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion

Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)

Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction

Explanation:

Step 1: Define

[Given] F = 3000 N

[Given] a = 15 m/s²

[Solve] m = x kg

Step 2: Solve for m

Substitute in variables [Newton's Second Law of Motion]:                          3000 N = m(15 m/s²)[Mass] [Division Property of Equality] Isolate m [Cancel out units]:            200 kg = m[Mass] Rewrite:                                                                                               m = 200 kg
