Question: A platform diver follows a parabolic trajectory during one of her dives. The diver enters the water at a horizontal displacement of 5 m from the end of the platform, and the diving platform is 10 m above the ground.
Part A: If she is in the air for 2.5 seconds, calculate the velocity and angle of takeoff of the diver.
I want help to calculate the velocity and angle of takeoff of the diver.
