Question

Find the mass of a car that has a speed of 30 m/s and a momentum of 45,000
kg*m/s.

Answer 1

Answer:

1,500 kg

Explanation:

p = mv

p is momentum

m is mass

v is velocity

p = mv

m = p ÷ v

45,000 ÷ 30 = 1,500 kg

Answer 2

The mass of the car: is 1500 kg.

Given the following data:

• Speed = 30 m/s.

• Momentum = 45,000  Kgm/s.

To find the mass of the car:

In Science, Momentum refers to the multiplication (product) of the mass of a physical object and its velocity.

Generally, momentum is a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

$Momentum = Mass$ × $Velocity$

Making mass the subject of formula, we have;

$Mass = \frac{Momentum}{Velocity}\\\\Mass = \frac{45000}{30}$

Mass = 1500 kg

Therefore, the mass of the car: is 1500 kg.
