Question

a body of mass 2 kg is travelling with a uniform velocity of 10 M per second what is its momentum question mark this body collides with another body of equal mass travelling in the same direction with a velocity of 5 metre per second what is the total momentum of the two bodies before collision? What is the total Momentum after collision ?

Answer 1

Momentum = mass × Velocity

Momentum of the body is :

2 × 10 = 20

20Kgms⁻¹

Momentum of the body that collides with it :

2 × 5 = 10

10Kgms⁻¹

Total momentum before collision = 10 + 20 = 30

= 30Kgms⁻¹

By law of conservation of momentum :

Initial momentum = final momentum.

The final momentum is thus 30Kgms⁻¹

Answer 2

Explanation:

your answer is 20 kgm/s , 30 kgm/s , 30 kgm/s
