A 5kg block is being pulled on a horizontal frictionless surface. The tension in the string is 30N. What is the total work done on the block as it moves a distance of 10 meters?
Thank you very much!
Just use the equation W=F*X since it is a flat surface. There is no friction that would counteract and make this more complex. The only forces acting on the block would be the tension.
In short, the work would be 300N*m or 300J, assuming that the problem is as simple as mentioned.
w=f*X
since it horizonal they won,t be friction
To calculate the total work done on the block, you can use the formula:
Work = force * distance * cos(theta)
In this case, the force is the tension in the string (30N), the distance is 10 meters, and cos(theta) is equal to 1 since the angle between the direction of the force and the direction of motion is 0 degrees (horizontal direction).
So, the total work done on the block is:
Work = 30N * 10m * 1
Work = 300 joules
Therefore, the total work done on the block is 300 joules.
To find the total work done on the block, we can use the formula:
Work = Force x Distance x Cos(theta)
where:
- Force is the applied force on the block
- Distance is the distance the block moves
- Cos(theta) is the angle between the applied force and the direction of motion (here, it is a horizontal motion, so theta is 0 degrees, and Cos(0) = 1)
In this case, the applied force on the block is the tension in the string, which is given as 30N. The distance the block moves is 10 meters.
Using the formula, we can calculate the total work done on the block:
Work = 30N x 10m x Cos(0)
= 30N x 10m x 1
= 300 Joules
Therefore, the total work done on the block as it moves a distance of 10 meters is 300 Joules.
