An 8 kg bowling ball is rolling in a straight line toward you. If its momentum is 16 kg·m/s, what is the velocity of the bowling ball?

A. 128 m/s
B. 24 m/s
C. 0.5 m/s
D. 2 m/s

Answer :

Option d is the right choice.

d. 2 m/s.

The momentum p of an object with mass m and velocity v is given by the formula:

[tex]\[ p = m \cdot v \][/tex]

Here, we're given that the bowling ball has a mass m = 8 kg and a momentum p = 16 kg·m/s.

We want to find the velocity v of the bowling ball. We can rearrange the formula for momentum to solve for velocity:

[tex]\[ v = \frac{p}{m} \][/tex]

Substituting the given values:

[tex]\[ v = \frac{16 \, \text{kg·m/s}}{8 \, \text{kg}} \][/tex]

v = 2 m/s.

So, the velocity of the bowling ball is 2 m/s.

The answer is 2 m/s.

Option d is the right choice.
