Adiver leaves the end of a 4.0 m high diving board and strikes the water 1.3 s later, 3.0 m beyond the end of the board. considering the diver as a particle, determine the maximum height reached (i solved for the initial velocity and degree above the horizontal. what do i do next? i have been looking at the big 5 for ever and i’m still stuck.)

let the diver has vertical speed as vy

now we can use kinematics to find out the vertical speed

as we know that

by solving above equation we have

now for finding the maximum height we will use kinematics equation

so the diver will move to 0.55 m high from his initial position
