A ball is projected upward at an initial velocity of the ball is 80.5 m/s, from a point on a flat roof 90 m above the ground. The ball rises and then falls missing the roof, and strikes the ground. Find the vertical velocity of the ball when it is 89 m above the ground is closest to

a. -81
b. -64
c. -48
d. -32
e. -97

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
