Question

a A body of mass 25kg, initially moving with a velocity of 10 m/s collide with
another body of mass 5kg at rest. After collision velocity of first body becomes
10 m/s. Find the velocity of the second body.

b. Name the scientific concept applied here.​

Answer 2

Explanation:

a. M1 =25 kg

U1 = 10 m/s

M2 = 5kg

U2 = 0 m/s

V1 = 10m/s

By the conservation of linear momentum,

M1 × U1 + M2 × U2 = M1 ×V1 + M2× V2

25×10 + 0 = 25 ×10 + 5 ×V2

250 =250 + 5× V2

0 = 5 ×V2

V2 = 0 m/s

b. Conservation of linear momentum
