A 50 kg trapeze artist falls from a height of 10 m, and has a speed of 14 m/s just before hitting the safety net. How much time is needed in order for them to stop if the maximum amount of force they can withstand is 500N?

Answer :

Answer:

t = 1.4 s

Explanation:

momentum of the trapeze just before hitting the net = 50 x 14 kg m/s

= 700 kg m/s

final momentum = 0

change in momentum required = 700 - 0 = 700

If F be the maximum force and t be the time of action of force

impulse = force x time = F x t

500 x t

impulse = change in momentum

500 x t = 700

t = 1.4 s .
