A drop of water falls from the gutter on your roof that is 7m
high. It took 1.2 seconds to fall
to the ground and it was going 11.76m/s. A) At t = 0.6s (half the
time) has the drop fallen more
than 3.5m, less than 3.5m, or 3.5m (half the distance)? B) At t =
0.6s (half the time) is the drop
going more than 5.88m/s, less than 5.88m/s, or 5.88m/s (half the
speed)?

question 22 and 25
25. A playground is on the flat roof of a city school, 6.00 m above the street below (Fig. P.25). The vertical wall of the building is h = 7.00 m high, forming a l-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launch ing it at an angle of = 58.0° above the horizontal at a point d=24.0m from the base of the building wall....

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.43 m/s. The stone subsequently falls to the ground, which is 11.7 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s2 for the acceleration due to gravity. impact speed: m/s How much time is the stone in the air?...

A steel ball is dropped from a building's roof and passes a window, taking 0.210 s to fall from the top to the bottom of the window, a distance of 1.80 m. It falls to a sidewalk and bounces back pass the window, moving from bottom to top in 0.210 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 3.00s. a) How tall is...
