Question

a rescue diver of mass 89 kg jumps from a hovering helicopter into the ocean below, what is the diver's speed (in m/s) when he hits the water

Answer 1

Need the HEIGHT of the helicopter to complete this answer

Step-by-step explanation:

PE (=mgh) is converted to KE ( = 1/2 mv^2 )

mgh = 1/2 m v^2

gh = 1/2 v^2

v^2 = 2 gh

v = sqrt (2gh) = sqrt ( 2 * 9.8 * h)
