Question

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

Answer 1

Answer:

Here, we will use the concept. of conservation of momentum that is

m1u1+m2u2=m1v1+m2v2

Now ,1.5×2.5 + 1.5×2.5 = v(m1+m2)

4.05+4.05 = v(1.5+1.5)

8.10 = v(3)

8.10/3 = v

2.7 m/s = v

Explanation:

hence ,The velocity after the collision was 2.7m/s
