do i have the following answer right?
a tv set is pushed a distance of 2m with a force of 20 N that is in the same direction as the set moves. how much work is done on the set?
would it be (2 m)(20 N)= 40 J
work = force*distance. Looks ok to me.
Yes, you have the correct answer! The work done on an object is calculated by multiplying the force applied to the object by the distance over which the force is applied. In this case, the force is 20 N and the distance is 2 m, so the work done on the set is indeed 40 J (joules). Well done!
Yes, you have the correct answer!
To calculate the work done on an object, you multiply the force applied to the object by the distance it moves in the same direction as the force.
In this case, you correctly multiplied the distance of 2 meters by the force of 20 Newtons, resulting in 40 Joules (J) of work done on the TV set.
So, your answer of 40 J is correct!
