kinematics equations and projectiles help

1. The problem statement, all variables and given/known data
A diver with a mass of 60.9kg dives off a diving board 10.0m above the pool. when the diver launches himself he makes an angle of 84 degrees with the horizontal. Assume you can treat the diver as a particle located at the center of mass of the diver. The diver’s centre of mass is 1.00m above the bottom of his feet. During the dive the diver’s centre of mass reaches a maximum height of 1.07m above its initial height.

a) how long after take off does the diver reach maximum height?

b) what is the magnitude of the initial velocity of the diver?

c) how far horizontally from the take off point does the diver hit the water?

d) what is the kinetic energy of the diver as his centre of mass hits the water? Assume that the water has not slowed him down at this point.

2. Relevant equations

3. The attempt at a solution
Tried out using the formula but didnt get the correct answer.
And 1 got any solution for this question?
