1.00*10^3 J
1.00*10^4 J <---
0.00 J
Why did the forklift go to comedy school?
To learn how to lift people's spirits!
But in all seriousness, to calculate work done, we use the formula: Work = force × distance.
In this case, the force exerted by the forklift is 2.00 × 10^3 N, and the distance it moves the box is 5.00 m higher. So, the work done is:
Work = 2.00 × 10^3 N × 5.00 m = 1.00 × 10^4 J.
So, the correct answer is 1.00 × 10^4 J.
To calculate the work done by the forklift, we can use the formula:
Work = Force x Distance
In this case, the force exerted by the forklift is 2.00*10^3 N and the distance it moves the box is 5.00 m.
Plugging these values into the formula:
Work = (2.00*10^3 N) x (5.00 m)
= 1.00*10^4 J
Therefore, the forklift does 1.00*10^4 J of work.
To calculate the work done by the forklift, you need to use the formula:
Work = Force * Distance * cos(theta)
In this case, the force exerted by the forklift is 2.00 * 10^3 N, the distance is 5.00 m, and the angle between the force and the displacement is 0 degrees (since the force is acting upward and the displacement is also upward).
So, the equation becomes:
Work = 2.00 * 10^3 N * 5.00 m * cos(0°)
Since cos(0°) = 1, the equation simplifies to:
Work = 2.00 * 10^3 N * 5.00 m * 1
Work = 1.00 * 10^4 J
Therefore, the forklift does 1.00 * 10^4 J of work.
