The power output, p, of a solar panel varies with the position of the sun. let p = 10sinθ watts, where θ is the angle between the sun's rays and the panel, 0 ≤ θ ≤ π. on a typical summer day in ann arbor, michigan, the sun rises at 6 am and sets at 8 pm and the angle is θ = πt/14, where t is time in hours since 6 am and 0 ≤ t ≤ 14. (a) write a formula for a function, f(t), giving the power output of the solar panel (in watts) t hours after 6 am on a typical summer day in ann arbor. (b) graph the function f(t) in part (a) for 0 ≤ t ≤ 14. (c) at what time is the power output greatest? what is the power output at this time? (d) on a typical winter day in ann arbor, the sun rises at 8 am and sets at 5 pm. write a formula for a function, g(t), giving the power output of the solar panel (in watts) t hours after 8 am on a typical winter day.

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.
