Asled is being pulled across a horizontal patch of snow. friction is negligible. the pulling force points in the same direction as the sled's displacement, which is along the +x axis. as a result, the kinetic energy of the sled increases by 47.9 percent. by what percentage would the sled's kinetic energy have increased if this force had pointed 68.6 ° above the +x axis?

17.47%

Explanation:

We can solve this problem through change in the Kinetic Energy,

Our Kinetic Energy at the beggining is,

After applying a force, the increase is given by

The change in the kinetic energy is given by

In this way, we know that the displacement of sled is,

When there is a positiving force of 68.6° we have in our Kinetic energy,

Substituting,

We can know define the % increased

they should be similar or the same

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
