Question

a 45 kg cheetah runs to the left at -14.9 m/s. what is its momentum?
←
p = ? kg·(m/s)
round your answer to the nearest tenth.
remember: p = m·v
enter the sign (+ or -) and the magnitude.

Explanation:

Step1: Identify formula and values

Momentum formula: \( p = m \cdot v \), where \( m = 45 \, \text{kg} \), \( v = -14.9 \, \text{m/s} \).

Step2: Calculate momentum

Substitute values: \( p = 45 \times (-14.9) \).
Calculate: \( 45 \times 14.9 = 670.5 \), so \( p = -670.5 \).

Answer:

-670.5
