At the player's maximum height, their velocity is 0. Recall that
which tells us the player's initial velocity 
is
The player's height at time 
is given by
so we find their airtime to be
Your answer will be False because wavelengths are usually are use as sound waves.
Work=f.d
Work=100*50 = 500
Power = work/time = 500/4
=125 watt

Answer:
450N
Explanation:
Given data
Mass m= 75kg
Acceleration= 6m/s^2
From the Newtons first law, F=ma
substitute
F=75*6
F= 450N
Hence the force is 450N
