Calculate the work done when a 15
kg object was lifted through a vertical distance of 300cm .
First, we need to convert the distance from cm to m:
300 cm = 3 m
The work done (W) is calculated with the formula:
W = Fd
where F is the force applied and d is the distance traveled.
In this case, the force applied is equal to the weight of the object, which is:
F = mg
where m is the mass of the object and g is the acceleration due to gravity (9.8 m/s^2).
F = 15 kg * 9.8 m/s^2
F = 147 N
Now we can calculate the work done:
W = Fd
W = 147 N * 3 m
W = 441 J
Therefore, the work done when a 15 kg object was lifted through a vertical distance of 300 cm is 441 J.
