Answer:
W = 8085.064 J
Step-by-step explanation:
given,
mass of the cheerleaders partner = 37.4 Kg
distance above which she was lift = 0.817 m
acceleration due to gravity = 9.8 m/s²
number of time she was picked = 27 times
work he done = ?
now,
Work done will be equal to the potential energy into number times she was lifted.
Work done = N m g h
W = 27 x 37.4 x 9.8 x 0.817
W = 8085.064 J
work done by his partner is equal to W = 8085.064 J
