Question

Two objects each of mass 1.5kg a moving in the same straight line be in opposite direction. The velocity of each object is 2.5m/s before the collision during with they stick together .What will be the velocity of thr combine object aftet collision . ​

Answer 1

Answer:

apply law of conservation of linear momentum in the line of action of collision and here coefficient of restitution is zero because both of the body stick together therefore after the collision both of them will stop.

Answer 2

Explanation:

M1 = m2 = 1.50 kg

v1 = 2.50 m/sec

v2 = - 2.50 m/sec

m1 v1 + m2 v2 = (m1 + m2) v

1.50 * 2.50 - 1.50 * 2.50 = 0 => v = 0

So the combined momentum is zero. so v = 0
