To learn about the Work-Energy Theorem and its basicapplications.

In this problem, you will learn about the relationship betweenthe work done on an object and the kinetic energy of thatobject.

The kinetic energy K of an object of massmmoving at a speed v is defined asK=(1/2)mv2. It seems reasonable to saythat the speed of an object--and, therefore, its kineticenergy--can be changed by performing work on the object.In this problem, we will explore the mathematical relationshipbetween the work done on an object and the change in the kineticenergy of that object.

H answer:

Fnet =12mv22?12mv12/s

I answer:

Wnet = Fnets

what is the answer for J.

Combine your results from Part H & Part I to find the network Wnet done on the sled.
