Question

Compare and contrast the trajectories of a diver leaving the 10m platform with A running take-off with a horizontal velocity of 3.0 ms-1

Answer 1

A diver of mass 65 kg takes off from the 10 m platform from a standing position by jumping upwards with a (near) vertical speed of 2.0 $m/s.$

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 $m/s.$

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

1). $x = 3t, y = 10+2t-0.5(9.8)t^2$

2). $x = 3cos60t, y = 10+3sin60t-0.5(9.8)t^2$
