Question

what is the force required to move a body of a rough inclined plane with uniform velocity​

Answer 1

Answer:

fine Mark as brainliest and also don't forget to follow me

Explanation:

The sign of work done by a force on a body is important to understand. State carefully if the following quantities are positive or negative: (a) work done by a man in lifting a bucket out of a well by means of a rope tied to the bucket. (b) work done by gravitational force in the above case, (c) work done by friction on a body sliding down an inclined plane, (d) work done by an applied force on a body moving on a rough horizontal plane with uniform velocity, (e) work done by the resistive force of air on a vibrating pendulum in bringing it to rest.

Answer 2

Explanation:

The force required to move a body up a rough inclined plane is double the force required to prevent the body from sliding down the plane.
