Calculating Momentum of a Car

Calculation of Momentum

A car of mass 800 kg is moving at a uniform velocity of 72 km/hr. Find its momentum.

Answer:

P = 16,000 kgm/s

Explanation:

Given :

Mass = m = 800 kg

Velocity = v = 72 km/hr = 20 m/s

Required :

Momentum = P = ?

Formula:

P = mv

Solution:

P = (800)(20)

P = 16,000 kgm/s

Question:

How do you calculate the momentum of a moving car?

Answer:

Momentum = Mass × Velocity

Mass = 800 kg

Velocity = 72 km/hr = 20 m/s

∴ Momentum = 800 × 20

= 16000 kgm/s
