Question

A 1,155 kg truck has a velocity of 18 m/s. What is the momentum of the truck?

Answer 1

The momentum of truck is 20790 kg m/s

Solution:

Given that we have to find the momentum of truck

From given, 1155 kg truck has a velocity of 18 m/s

Therefore,

Mass = 1155 kg

Velocity = 18 m/s

The momentum is given by formula:

$p = m \times v$

Where, m is mass in kg and v is velocity in m/s

Substituting the values we get,

$p = 1155 \times 18\\\\p = 20790$

Thus momentum of truck is 20790 kg m/s
