Question
A forklift exerts a force of 12,000 N to lift a box 4 ,meters in 3 ,seconds. What is the power ,produced by the forklift? A. 9,000 J/s B. 16,000 J/s C. 36,000 J/s D. 144,000 J/s
Solution
The power produced by the forklift can be calculated using the formula for power:
Power = Work / Time
First, we need to calculate the work done by the forklift. Work is defined as the force applied to an object times the distance over which it is applied. In this case, the force is 12,000 N and the distance is 4 m.
Work = Force x Distance Work = 12,000 N x 4 m Work = 48,000 Joules
Next, we divide the work done by the time it took to do the work to find the power. The time given is 3 seconds.
Power = Work / Time Power = 48,000 J / 3 s Power = 16,000 J/s
So, the power produced by the forklift is 16,000 J/s. The correct answer is B. 16,000 J/s.
