Question

How fast is a 150 kg object going if its momentum is 600 kg m/s?

Answer 1

Answer:

v = 4 m/s

General Formulas and Concepts:

Momentum

Momentum Formula: p = mv

• p is momentum (in kg · m/s)
• m is mass (in kg)
• v is velocity (in m/s)

Explanation:

Step 1: Define

Identify variables

[Given] p = 600 kg · m/s

[Given] m = 150 kg

[Solve] v

Step 2: Solve for v

1. Substitute in variables [Momentum Formula]:                                                600 kg · m/s = (150 kg)v
2. Isolate v [Cancel out units]:                                                                              4 m/s = v
3. Rewrite:                                                                                                             v = 4 m/s
