A ball is projected upward at time t=0 s, from a point on a flat roof 90 m above the ground. The ball rises and then falls with insignificant air resistance, missing the roof, and strikes the ground. The initial speed of the ball is 80.5 m/s. Consider all quantities as negative in the upward direction. The vertical velocity of the ball when it is 89 m above the ground is closest to Select one: © A 80 m/s. OB. 81 m/s. OC. 81 m/s OD. -64 m/s. OE. -48 m/s. OF. -80 m/s.
