Question

please give me answer.​

Answer 1

Explanation:

Total mass of lorry with its goods,m = 4000+20000= 24000 kg

velocity,v = 2m/s

momentum =mv= 24000*2= 48000kg m/s

Answer 2

Answer:

Momentum of the lorry = 48000 kg m/s.

Explanation:

Given :

• Mass of a goods lorry = 4000kg
• Mass of goods loaded on it = 20000kg
• Lorry is moving with a velocity = 2m/s

To Find :

• Momentum of the lorry

Solution :

Total mass on lorry = Mass of goods lorry + Mass of goods loaded on it

= 4000 kg + 20000 kg

= 24000 kg

We know that :-

Momentum (p) = Mass (m) × Velocity (v)

Therefore,

p = 24000 kg × 2 m/s  

p = 48000 kg m/s

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