a giant robot tosses a ball up, from a height of 80 meters, with an initial velocity of Vo = 60 m/s, use 10 m/s^2 as the acceleration due to gravity.

what will be the minimum velocity of the ball and when and where will that occur? [i don't know how you would find that.]

what will be the maximum speed, and when and where will that occur/

how many times can the ball attain a speed greater than 60 m/s but less that its maximum speed?
