Question

Answer the 4 th question!​

Answer 1

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.

Answer 2

Answer:

Given :    m  

1

​

=4000 kg           m  

2

​

=20000 kg             v=2 m/s

Total mass of the 'lorry + goods' system      M=4000+20000=24000 kg

∴ Total momentum of the system        P=Mv=24000×2=48000  kg m/s
