Answer:
The work done by the man is 260 J.
(E) is correct option.
Explanation:
Given that,
Force = 80 N
Distance = 5.0 m
Angle = 30°
Acceleration = 1.5 m/s²
Let F be the man's force
We need to calculate the force
Using balance equation




We need to calculate the work done by the man
Using formula of work done



Hence, The work done by the man is 260 J.

BYE- a person who has never had sexual intercourse.
Explanation:
Answer:
75Watts
Explanation:
Given parameters:
Time = 12s
Force applied = 20N
Height = 45m
Unknown:
Power output = ?
Solution:
Power is defined as the rate at which work is done.
It is mathematically expressed as;
Power =
Work done = force x distance = 20 x 45 = 900J
Power =
= 75Watts
