Jumping from a 10 m high platform and hitting the water at a speed of 30 mph is a daunting enough prospect on its own. But when you have to throw in a series of somersaults and twists in between , and land with only the slightest splash , there is little margin for error.

a) Compare and contrast the trajectories of a diver leaving the 10 m platform with 

i) A running take - off with a horizontal velocity of 3.0 ms-1

ii) A running take-off with a velocity of 3.0 ms-1 with an angle of 60 degrees

b) Explain how the position adopted in flight would affect the trajectory of the diver
