Question

1. a ball has 2 kg*m/s of momentum when thrown with a velocity of 5 m/s outwards. find the mass of the ball.

Explanation:

Step1: Recall the formula for momentum

Momentum \(p = mv\), where \(p\) is momentum, \(m\) is mass and \(v\) is velocity.
Given \(p = 2\space kg\cdot m/s\) and \(v=5\space m/s\).

Step2: Solve for mass \(m\)

Rearrange the formula \(m=\frac{p}{v}\).
Substitute the values: \(m = \frac{2\space kg\cdot m/s}{5\space m/s}\).

Answer:

\(m = 0.4\space kg\)
