Question

a 15 kg object has a momentum of 150 kg·m/s north. what is the objects velocity? a. 0.1 m/s b. 10 m/s c. 2,250 m/s d. 135 m/s

Explanation:

Step1: Recall the momentum formula

Momentum formula is \( p = mv\), where \( p\) is momentum, \( m\) is mass, and \( v\) is velocity. We need to solve for \( v\), so \( v=\frac{p}{m}\).

Step2: Substitute the given values

Given \( p = 150\space kg\cdot m/s\) and \( m = 15\space kg\). Then \( v=\frac{150}{15}\).

Step3: Calculate the velocity

\( v = 10\space m/s\)

Answer:

B. \(10\space m/s\)
