The mass of a goods lorry is 4000 kg and the mass of goods loaded on i

1.	The mass of a goods lorry is 4000 kg and the mass of goods loaded on it is 20000 kg. If the lorry is moving with a velocity of 2 m/s, what will be its momentum ?
Answer» Given, Velocity (v) = 2 m/s Mass of lorry = 4000 kg, Mass of goods on the lorry = 20000 kg Therefore, Total mass (m) on the lorry = 4000 kg + 20000 kg = 24000 kg Momentum (p) = ? We know that, Momentum (p) = Mass (m) × Velocity (v) Therefore, p = 24000 kg × 2 m/s Or p = 48000 kg m/s Thus, the momentum of the lorry = 48000 kg m/s.

The mass of a goods lorry is 4000 kg and the mass of goods loaded on it is 20000 kg. If the lorry is moving with a velocity of 2 m/s, what will be its momentum ?

Answer»

Given, Velocity (v) = 2 m/s

Mass of lorry = 4000 kg, Mass of goods on the lorry = 20000 kg

Therefore, Total mass (m) on the lorry = 4000 kg + 20000 kg = 24000 kg

Momentum (p) = ?

We know that, Momentum (p) = Mass (m) × Velocity (v)

Therefore, p = 24000 kg × 2 m/s

Or p = 48000 kg m/s

Thus, the momentum of the lorry = 48000 kg m/s.
