Question

a 0.1 kg shuttlecock moves to the left at -12.3 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 the formula for momentum

The formula for momentum \( p \) is given by \( p = m \cdot v \), where \( m \) is the mass and \( v \) is the velocity.

Step2: Substitute the given values into the formula

We are given that the mass \( m = 0.1 \, \text{kg} \) and the velocity \( v = -12.3 \, \text{m/s} \). Substituting these values into the formula, we get:
\( p = 0.1 \, \text{kg} \times (-12.3 \, \text{m/s}) \)

Step3: Calculate the momentum

Multiplying \( 0.1 \) by \( -12.3 \), we have:
\( p = -1.23 \, \text{kg} \cdot \text{m/s} \)

Step4: Round to the nearest tenth

Rounding \( -1.23 \) to the nearest tenth gives \( -1.2 \, \text{kg} \cdot \text{m/s} \).

Answer:

\( -1.2 \)
