Question

Question: At a water park, Hugo climbs a 15.00m springboard, in 22.00s, to execute his famous THUNDER CANNON BALL. Hugo jumps up at 6.000m/s [up] off the end of the diving board and propels his mass, of 85.00kg towards the water.
calculate the...
1.weight of Hugo,
2.work done getting to the 15.00m board,
3.potential energy gained at boards edge,
4.power generated in climbing the boards edge,
5.kinetic energy in jumping upwards at the boards edge,
6.max height attained above the board,
7.max height above the water,
8.total energy at max height and
9.speed striking the water.
