You carry a 7.0 kg bag of groceries above the level floor at a constant velocity of 75 cm/s across a room that is room. how much work do you do on the bag in the process?
a) 158 j
b) 82 j
c) 134 j
d) 0.0 j

Work done, W = 0

Explanation:

It is given that,

Mass of the bag, m = 7 kg

Speed of the person, v = 75 cm/s (constant)

To find,

Work done

Solution,

The product of force and displacement is called work done. It is given by :

is the angle between force and displacement

Here, the person carries a bag and moving with constant velocity. It means that the angle between force and displacement is 90 degrees.

W = 0

So, the work done by the person on the bag in the process is equal to 0. Therefore the correct option is (d).

i think the answer is a, hope this is right, that would be my best guess.

i believe the answer is electric potential.
