Two objects each of mass 1.5 kg are moving

Asked by admin @ 16/08/2021 in Physics viewed by 300 People

Two objects, each of mass 1.5 kg, are moving in the same straight line but in opposite directions. The velocity of each object is 2.5 m s-1 before the collision during which they stick together. What will be the velocity of the combined object after collision?

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.
