Question

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

Answer 1

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)

Step-by-step 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
