Question

a bowling ball has a mass of 6 kg. what happens to its momentum when its speed increases from 2 m/s to 4 m/s? the initial momentum is 12 kg·m/s, and the final momentum is 3 kg·m/s. the initial momentum is 6 kg·m/s, and the final momentum is 3 kg·m/s. the initial momentum is 12 kg·m/s, and the final momentum is 24 kg·m/s. the initial momentum is 6 kg·m/s, and the final momentum is 12 kg·m/s.

Explanation:

Step1: Calculate initial momentum

Momentum formula: \(p = mv\). Given \(m = 6\space kg\), \(v_{initial}=2\space m/s\). Then \(p_{initial}=6\times2 = 12\space kg\cdot m/s\).

Step2: Calculate final momentum

Given \(m = 6\space kg\), \(v_{final}=4\space m/s\). Then \(p_{final}=6\times4 = 24\space kg\cdot m/s\).

Answer:

The initial momentum is \(12\space kg\cdot m/s\), and the final momentum is \(24\space kg\cdot m/s\).
