Question

A car with a mass of 1,100 kg is moving with a velocity of 30 m/s due east. What is its momentum?

A.3,300 kg·m/s east
B.33,000 kg·m/s east
C.36 kg·m/s, east
D.120,000 kg·m/s east

Answer 1

The answer is B. 33,000kg.m/s East.

Momentum can calculated by getting the product of mass and velocity. The formula is:


`p=mv`

Where:
p=momentum
m = mass
v = velocity

The given in your problem are:
m = 1,100kg
v = 30m/s (East)

Just plug in your given in the formula and solve:


`p=mv`

`=(1,100kg)(30m/s)`

`=33,000kg.m/s` East
