In summary, a man is pushing back on a 280kg piano that is sliding 4.3 meters down a 30 degree incline with an effective coefficient of kinetic friction of .40. The man is exerting a force to keep the piano from accelerating, and the sum of all forces on the piano is 0. The homework asks for the calculation of the force exerted by the man, the work done by the man on the piano, the work done by the friction force, the work done by the force of gravity, and the net work done on the piano. The student is unsure of where to start and is advised to draw the forces on the piano and use the fact that the sum of all forces is 0

Homework Statement



A 280kg piano slides 4.3 meters down a 30 degree incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is .40. Calculate: a) The force exerted by the man. b) The work done by the man on the piano. c) the work done by the friction force. d) The work done by the force of gravity. e) The net work done on the piano

Homework Equations



Well I know since it's kept from accelerating, the sum of all forces of work is 0.

The Attempt at a Solution



I honestly don't know where to start.

Draw the forces on the piano. You know what they all sum to.
 

Related to Solving a Ramp Problem: Calculating Forces and Work Done on a Sliding Piano

What is a ramp problem?

A ramp problem is a physics problem that involves calculating the motion of an object on a ramp. It typically involves finding the acceleration, velocity, or displacement of the object as it moves up or down the ramp.

What are the key concepts to understand in solving a ramp problem?

The key concepts to understand in solving a ramp problem are the forces acting on the object, such as gravity and normal force, and the relationship between these forces and the angle of the ramp.

What type of equations are used to solve a ramp problem?

Equations of motion, such as Newton's Second Law and the equations for constant acceleration, are used to solve ramp problems. Trigonometric functions may also be used to calculate the forces and angles involved.

What are some common mistakes made when solving a ramp problem?

Some common mistakes made when solving a ramp problem include using incorrect equations, not properly considering all the forces acting on the object, and not paying attention to units and their conversions.

How can I improve my problem-solving skills for ramp problems?

To improve your problem-solving skills for ramp problems, it is important to understand the underlying concepts and equations involved. Practice solving different types of ramp problems, and make sure to double-check your calculations and units. It can also be helpful to work through problems with a study group or seek guidance from a tutor or teacher.
