Help Wanted ~ 50 Points! A diver jumps up off the 10 meter tower and spends 1.63 seconds in the air. How fast was she going when her feet left the diving tower? How fast is she going just before she hits the water?
The diver has a speed of as she leaves the tower.
The diver has a speed of just before she hits the water.

This is kenetic energy.

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
