Answer 2

$\bf{\underline{\underline{SOLUTION:}}}$

Since two objects of equal masses are moving in opposite direction with equal velocity therefore, the velocity of the objects after collision during which they stick together will be zero.

$\bf{\underline{\underline{Step\: by\: step \:explanation:}}}$

$\bf{\underline {Given:}}$

Mass of first object, $m_1=1.5\:kg$

Initial velocity of one object, $u_1=2.5\:m\:s^{-1}$

Initial velocity of second object, $u_2 = - 2.5 \:m\:s^{-1}$

( since second object is moving in opposite direction)

$\bf{\underline {To\:find:}}$

Final velocity of both the objects which stick after collision, $v =\:?$

We know that,

$m_1u_1+m_2u_2=m_1v_1+m_2v_2$

Substituting the values, we get

$1.5 ×2.5+1.5×(-2.5)=1.5 × v + 1.5 × v$

$3.75-3.75 = v (1.5+1.5)$

$v = \dfrac{0}{3.00}= 0$

Therefore final velocity of both the objects after collision will become zero.
