Question

a 12.0 kg lizard runs to the left at -6.8 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 given values

Mass $m = 12.0\ \text{kg}$, velocity $v = -6.8\ \text{m/s}$

Step2: Apply momentum formula

Use $p = m \cdot v$
$p = 12.0 \times (-6.8)$

Step3: Calculate and round result

$p = -81.6$ (already to nearest tenth)

Answer:

$-81.6\ \text{kg} \cdot \frac{\text{m}}{\text{s}}$
