Answer:
The answer to your question is 1.35 Watts
Explanation:
Data
Work = W = 5 J
time = t = 3.7 s
Power = P = ?
Formula
Power is a rate in which work is done or energy is transferred over time
P =
Substitution
Result
P = 1.35 W
The force must be at least 245 N
Explanation:
The force needed to lift the mass is at least equal to the force of gravity acting on the mass (also known as the weight of the object).
The weight of an object is given by
where
m is the mass of the object
is the acceleration of gravity at the Earth's surface
The mass of the object in the problem is
m = 25 kg
So, its weight is
Therefore, the force to lift the object must be at least equal to 245 N.
