A total of 650 joules of work is done on a 50.-kilogram object as it is moved 8.0 meters across a level floor by the application of a horizontal force. Determine the magnitude of the horizontal force applied to the object
Given
W = 650 J
m = 50 kg
d = 8.0 m
work= force*distance
force=work/distance= 650J/8m= you do it, answer is in newtons.
Ok, thanks got it i was a little confused on that. It's 80 J
isn't it 80 N?
To determine the magnitude of the horizontal force applied to the object, we need to use the work-energy principle, which states that the work done on an object is equal to the change in its kinetic energy.
The work done on the object can be calculated using the formula:
Work = Force * Distance
In this case, the work done is given as 650 joules, and the distance traveled is 8.0 meters.
So, we can rearrange the formula to solve for the force:
Force = Work / Distance
Substituting the given values:
Force = 650 J / 8.0 m
Calculating:
Force ≈ 81.25 Newtons
Therefore, the magnitude of the horizontal force applied to the object is approximately 81.25 Newtons.
