A Ball Is Projected Upward at Time T = 0 $58.5 \mathrm {~m} / \mathrm { s }$

Multiple Choice

A ball is projected upward at time t = 0 s,from a point on a flat roof 10 m above the ground.The ball rises and then falls,missing the roof,and strikes the ground.The initial velocity of the ball is $58.5 \mathrm {~m} / \mathrm { s }$ Consider all quantities as positive in the upward direction.Neglect the effects of air.At time $t = 5.97 \mathrm {~s} ,$ the vertical velocity of the ball is closest to

A) 0 m/s.
B) +175 m/s.
C) +12 m/s.
D) -175 m/s.
E) -12 m/s.
