Question

The mass of goods lorry is 5500 kg and the mass of goods loaded on it is 10000 Kg if the lorry is moving with a velocity of 2 metre per second what will be its momentum​?

Answer 1

Given, Velocity (v) = 2m/s Mass of lorry = 5500 kg, Mass of goods on the lorry = 10000 kg Therefore, total mass (m) of the lorry = 5500 kg + 10000 kg = 15500 kg Momentum (p) =? Momentum (p) = Mass (m) x Velocity (v) Therefore, p = 15500 kg x 2 m/s = 31000 kg m/s Thus, momentum of the lorry = 31000 kg m/s.

Answer 2

Question:-

The mass of goods lorry is 5500 kg and the mass of goods loaded on it is 10000 Kg if the lorry is moving with a velocity of 2 metre per second what will be its momentum?

${\red{\underline{\underline{\bold{AnsweR:-}}}}}$

Given :

Mass of a goods lorry = 5500 kg

Mass of goods = 10,000kg

Velocity of the loaded lorry = 2ms¯¹

To Find :

Momentum

Formula used :

Momentum = mass × velocity

Solution :

Mass of lorry = 5500 kg

Mass of goods = 10,000kg

Total mass of loaded lorry(m) =10,000+5,500

= 15,500 kg

And,

Velocity of the loaded lorry (v) = 2ms¯¹

Now,

Momentum = m× v

= 15,500 × 2

= 31,000 kgms¯¹

Therefore, the momentum of the loaded lorry is 31,000 kgms¯¹.

OR

Given,

Velocity (v) = 2m/s Mass of lorry = 5500 kg,

Mass of goods on the lorry = 10000 kg

Therefore,

total mass (m) of the lorry = 5500 kg + 10000 kg = 15500 kg Momentum (p)

=? Momentum (p) = Mass (m) x Velocity (v)

Therefore,

p = 15500 kg x 2 m/s = 31000 kg m/s

Thus, momentum of the lorry = 31000 kg m/s.

hope it helps you.
