Question

1. a ball has 2 kg*m/s of momentum when thrown with a velocity of 3 m/s. what is the mass of the ball.

Explanation:

Step1: Recall the formula for momentum

The formula for momentum \(p = mv\), where \(p\) is momentum, \(m\) is mass and \(v\) is velocity. We need to find \(m\), so we can re - arrange the formula to \(m=\frac{p}{v}\).

Step2: Substitute the given values

Given \(p = 2\space kg\cdot m/s\) and \(v = 3\space m/s\). Substitute these values into the formula \(m=\frac{p}{v}\), so \(m=\frac{2}{3}\space kg\approx0.67\space kg\)

Answer:

The mass of the ball is \(\frac{2}{3}\space kg\) (or approximately \(0.67\space kg\))
