Aball is thrown straight up from the edge of the roof of a building. a second ball is dropped from the roof a time of 1.03 s later. you may ignore air resistance. a-if the initial speed of the first ball is v0 = 8.90 m/s what must the height h of the building be for both balls to reach the ground at the same time?
b-if v0 is greater than some value vmax, a value of h does not exist that allows both balls to hit the ground at the same time. solve for vmax
c-if v0 is less than some value vmin, a value of h does not exist that allows both balls to hit the ground at the same time. solve for vmin.

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
