Question

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 metre per second before the collision during which stick together. What will be the velocity of the combined object after collision?​

Answer 2

Explanation:

$\huge\pink{Hey \: Guys}$

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.
