1. A dog sees a flowerpot sail up and then back down a window (height of window is 1.77m). If the total time the pot is in sight for 1.0 s, find the height above the top of the window to which the pot rises.

2. A runner hopes to complete a 10-km run in 30.0 min. After exactly 27.0 min there is still 1100 m to go. The runner must then accelerate at 0.20 m/s^2 for how many seconds in order to exactly acheive his desired time?

Thanks in advance
