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

question 99

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 with insignificant air resistance, 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. 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.
