Answer:
Average power output of athlete = 11025 Watts
Explanation:
Work done is defined as the product of force applied and the displacement perpendicular to the force.
Work =
Power is defined as work done per unit time.
Power =
Here the person lifts 900 kg.
Height = 2.5 m
Time interval = 2 seconds
Force =
=
= 8820 N
Work done =
=
= 22050 J
Power =
= 11025 Watt
Actually Welcome to the Concept of the Kinematics.
so here we get as,
V^2 = U^2 + 2as
so here, a = -0.2 m/s^2
(0.1)^2 = (0.3)^2 + (-0.2)(s)
=> 0.01 = 0.09 - 0.2s
=> 0.2s = 0.08
=> s = 0.08/0.2
=> s = 0.4 m
