Find the work done in pushing a 120 kg box for 5 meters across the floor. W=F * D (F=m*g)
a. 600.0 J
b. 5,880.0 J
c. 5,008.8 J
d. 601.5 J
To find the work done in pushing a box across the floor, you can use the equation W = F * D, where W represents work, F represents the force applied, and D represents the distance moved.
In this case, the force applied can be calculated using the formula F = m * g, where m represents the mass of the box and g represents the acceleration due to gravity (approximately 9.8 m/s^2).
Given that the mass of the box is 120 kg and the distance moved is 5 meters, we can calculate the force applied as follows:
F = m * g
F = 120 kg * 9.8 m/s^2
F ≈ 1176 N
Now that we have the force applied, we can use it along with the distance moved to calculate the work done:
W = F * D
W = 1176 N * 5 m
W = 5880 J
Therefore, the work done in pushing the 120 kg box for 5 meters across the floor is 5880 J.
The correct answer is:
b. 5,880.0 J
