PLEASE OM When describing image formation for plane mirrors, what is an important rule to remember about light rays? A. The angle when it leaves is the same as the angle when it hits.
B. The angle is smaller in the medium that has the lower index of
refraction
C. The angle when it leaves is larger than the angle when it hits.
D. The angle is smaller in the medium that has the higher index of
refraction

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
