A sled with mass 15 kg moves in a straight line on a horizontal surface as it is being pulled by a force F at an angle of 30° with the direction of motion. A force of friction of 10 N acts on the sled. At one point in its path, its speed is 4.0 m/s; after it has traveled a distance 5.0 m beyond this point, its speed is 7.0 m/s. Use the work-energy theorem to find the total work done on the sled?
Find the pulling force F on the sled.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
