1.	A body is projected vertically up with a velocity v and after some time it returns to the point from which it was projected. The average velocity and average speed of the body for the total time of flight areA. `(vec v)/(2) and (v)/(2)`B. `0 and (v)/(2)`C. `0 and 0`D. `(vec v)/(2) and 0`.
Answer» Correct Answer - B Average velocity = `0` because net displacement of the body is zero. Average speed `= ("Total distance covered")/("Time of flight")` =`(2 H_(max))/(2 u//g)` `rArr v_(av) = (2 u^2//2g)/(2u//g) rArr v_(av) = (u)/(2)` Velocity of projection = v (given) `:. v_(av) = (v)/(2)`.
