Solution

The correct option is A $0$
As we know area under velocity-time graph gives displacement of an object. Here the graph is forming two different triangles of same area but in opposite quadrant. So summation of the the area of the two triangle becomes zero. (as the sign is opposite of both). Thus the average velocity is zero

Two objects of masses 100 g and 200 g are moving along the same line and direction with velocities of 2 ms⁻¹ and 1 ms⁻¹, respectively. They collide and after the collision, the first object moves at a velocity of 1.67 ms⁻¹. Determine the velocity of the second object.

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 the collision?
