Question

a bowling ball has a mass of 5 kg
what happens to its momentum when its speed increases from 1 m/s to 2 m/s?
o the initial momentum is 5 kg·m/s, and the final momentum is 20 kg·m/s
o the initial momentum is 5 kg·m/s, and the final momentum is 3 kg·m/s.
o the initial momentum is 5 kg·m/s, and the final momentum is 7 kg·m/s
o the initial momentum is 5 kg·m/s, and the final momentum is 10 kg·m/s

Explanation:

Step1: Calculate initial momentum

Momentum formula: $p = mv$. Given $m = 5\ kg$, $v_{initial}=1\ m/s$.
$p_{initial}=5\times1 = 5\ kg\cdot m/s$

Step2: Calculate final momentum

Given $v_{final}=2\ m/s$.
$p_{final}=5\times2 = 10\ kg\cdot m/s$

Answer:

The initial momentum is $5\ kg\cdot m/s$, and the final momentum is $10\ kg\cdot m/s$
