Two cars A and B are moving in opposite directions with the speed of 10 m/s and 20 m/s respectively. Find (i) VAB(ii) VBA And also draw the diagram to represent the motion of the car.​

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
