A steel ball whose mass is 2.0 kg is rolling at a rate of 2.8 m/s. What is its momentum?

Momentum is mass x velovity

5.6

The momentum of an object is defined as the product of its mass and velocity.

Given that the mass of the steel ball is 2.0 kg and its velocity is 2.8 m/s, we can calculate its momentum using the formula:

Momentum = mass × velocity

Substituting the given values, we have:

Momentum = 2.0 kg × 2.8 m/s

Calculating this expression gives us:

Momentum = 5.6 kg*m/s

Therefore, the momentum of the steel ball is 5.6 kg*m/s.

To find the momentum of the steel ball, you can use the formula:

Momentum = mass × velocity

First, we need to identify that the mass of the steel ball is given as 2.0 kg and the velocity or rate at which it is rolling is 2.8 m/s.

Now, we can calculate the momentum.

Momentum = 2.0 kg × 2.8 m/s

Simply multiply the mass (2.0 kg) by the velocity (2.8 m/s) to get the momentum.

Momentum = 5.6 kg · m/s

Therefore, the momentum of the steel ball is 5.6 kg·m/s.
