An orange is falling from a bridge that is 35 m above the water level. Free fall is an accelerated motion with a = 9.8 m/s2. It lands on a boat that is moving under the bridge with a constant speed. At the moment when the orange was let free, the boat was 15 m far from the place of its impact. What is the speed of the boat?

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head.
