Questions
A particle is projected vertically upward with velocity u from a point A, when it returns to the point of projection
detailed solution
Correct option is A
For vertically projected body, if it returns to the starting point, displacement and average velocity become zero. As acceleration is constant, average speed during upward or downward motion is (u+0)/2=u/2. The same will be the average speed for the whole motion.Talk to our academic expert!
