Question

A car of mass 1800 kg is moving with a velocity of 60 km h-1 . Calculate the momentum of the car.

Answer 1

Given :-

• Mass of car = 1800 kg
• Velocity of the car = 60 km/h

To find :-

• Momentum = ?

Solution :-

Firstly converting 60 km/h → m/s

To convert we have to multiply with 5/18

→ 60 × 5/18

→ 300/18

→ 16.66 m/s

Finding momentum using

p = m × v

Where

• p → momentum = ?
• m → mass = 1800 kg
• v → velocity = 16.66 m/s

Substituting the values we have

→ p = 1800 × 300/18

→ p = 100 × 300

→ p = 30000 pascal (pa)

Hence , momentum of the car = 30 × 10³ pa.
