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 Step-by-step explanation:

Step 1: Define

[Given] F = 20.0 N

[Given] a = 5.0 m/s²

[Solve] Mass m

Step 2: Solve for m

Substitute in variables [Newton's 2nd Law of Motion]:                               20.0 N = m(5.0 m/s²)[Division Property of Equality] Divide 5.0 on both sides:                            4.00 kg = mRewrite:                                                                                                           m = 4.00 kg

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.
