Question

1. a 25 kg cart has 120 kg*m/s of momentum. how fast is the cart going?

Explanation:

Step1: Recall the momentum formula

The formula for momentum \(p = mv\), 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 \(p = 120\space kg\cdot m/s\) and \(m = 25\space kg\). Then \(v=\frac{120}{25}\).

Step3: Calculate the value of \(v\)

\(v = 4.8\space m/s\)

Answer:

The cart is going at a speed of \(4.8\space m/s\).
