Question

The magnitude of the momentum of an object is the product of its mass m and speed v. If m = 3 kg and v = 1.5 m/s, what is the magnitude of the momentum? Be sure to give the correct number of significant figures in your answer.

Answer 1

Momentum, p = 5 kg-m/s

Step-by-step explanation:

The magnitude of the momentum of an object is the product of its mass m and speed v i.e.

p = m v

Mass, m = 3 kg

Velocity, v = 1.5 m/s

So, momentum of this object is given by :

`p=3\ kg* 1.5\ m/s`

p = 4.5 kg-m/s

or

p = 5 kg-m/s

So, the magnitude of momentum is 5 kg-m/s. Hence, this is the required solution.
