C - A dog runs an average of 8 mph. Speed is scalar.

Barbara Oconnor · Answer 2

A dog sees a flowerpot sail up and then back past a window 2.00 m high. If the total time the pot is in sight is 1.00 s (0.50 s on the way up and 0.50 s on the way back down), find the height above the top of the window to which the pot rises. (Halliday and Resnick, third edition, chapter 2, problem 85P).
