discosucks said:Im thinking its the work equation but this is were i got stuck
Where did you get that formula?discosucks said:W = m(as)
That's the equation that you need. What's "F" in this problem?discosucks said:work is when a force moves its point of application through a distance .
isnt that the same as W = Fs?
Doc Al said:That's the equation that you need. What's "F" in this problem?
What force? (What force is doing the work in this problem?)discosucks said:force?
No. Mass x acceleration gives you the net force on something.discosucks said:and that would be the mass x the acceleration
The acceleration would be zero.discosucks said:but what do i say the acceleration is seeing as I am told its constant?
discosucks said:Im pretty confused now lol but I'm going to say its gravitational force bearing down ?
You're asked to find the work done by the tension, so you need the tension. (Since the acceleration is zero, that tension will equal the weight of the object.)discosucks said:Im pretty confused now lol but I'm going to say its gravitational force bearing down ?
Yes.discosucks said:So its just the weight by the distance seing as the acceleration is zero?
1250 is not the weight.discosucks said:1250 x 8 = 10000 J ?
The work done by the tension on a cable refers to the energy required to move an object against the force of tension exerted by the cable. It is a measure of the force and distance involved in moving the object.
The work done by the tension on a cable is calculated by multiplying the force exerted by the cable by the distance the object is moved in the direction of the force. This formula can be represented as W = F x d, where W is the work done, F is the tension force, and d is the distance.
Yes, the direction of the tension force does affect the work done by the cable. The work done will be positive if the force and displacement are in the same direction, and negative if they are in opposite directions. This is because work is a scalar quantity and does not take into account the direction of the force.
The angle of the cable affects the work done by the tension force by changing the effective force acting in the direction of displacement. The component of the tension force in the direction of displacement will be greater if the cable is at a smaller angle, resulting in more work being done.
No, the work done by the tension on a cable is not always equal to the work done on the object. This is because there may be other forces acting on the object, such as friction, that also do work. The work done by the tension only accounts for the energy required to move the object against the force of tension.
