How Much Work is Done Pushing a Sled Up an Incline?

In summary, the question asks about the amount of work done when a father pushes his daughter and sled up a snowy incline with a constant velocity. The combined mass of the child and sled is 35kg, there is a friction coefficient of 0.2 between the snow and skids, and the incline is at 15 degrees with a distance of 10m. The work can be calculated by finding the force (N=mg) and then finding the component of that force in the direction of motion (Ncos15 degrees). The attempt at a solution involved calculating the force (343N) and then finding the component of that force (329.7N

Homework Statement


FATHER PUSHs IS DAUGHTER ON A SLED UP A SNOWY INCLINE. IF THE SLED MOVES UP THE HILL WITH A CONSTANT VELOCITY how MUCH WORK IS DONE?
CHILD & SLED= 35KG FRICTION OF SNOW & SKIDS= .2 INCLINE= 15 DEGREES, d=10 m

Do i need to find the force? (N=mg)
and then Ncos15degrees?


The Attempt at a Solution


I don't know how to get started.

Have you made any attempt to answer this question? You must show some work before we can help you. Also, in future, would you please write in lower case: upper case is considered to be shouting.

Yes I have, but I'm not getting the same answer as in the book.
Sorry about the upper caps.

35kg*9.8= 343N
343N cos 15 degrees = .97

What is the definition of work?

definiton of work is W=Fd

or W=Fd = (Fcos thete)
 

What is work done on an incline?

Work done on an incline refers to the amount of energy required to move an object along a ramp or slope against the force of gravity.

How is work done on an incline calculated?

Work done on an incline can be calculated by multiplying the force applied to the object by the distance over which it is moved along the incline.

What factors affect the amount of work done on an incline?

The amount of work done on an incline is affected by the mass of the object being moved, the angle of the incline, and the force applied to the object.

What is the relationship between work done on an incline and energy?

Work done on an incline is a measure of the energy required to move an object along a slope. It is directly proportional to the amount of energy used in overcoming the force of gravity.

How is work done on an incline used in real-world applications?

The concept of work done on an incline is commonly used in physics and engineering to calculate the amount of energy needed to move objects up or down ramps, hills, or other inclined surfaces. It is also used in industries such as construction and transportation to determine the effort required for moving materials and goods.
