A60-kg skier starts at the top of a 10-meter high slope. at the bottom, she is traveling 10m/s. how much energy does she lose to friction?
pl !

Use conversion:

As per the given statement:

Mass of the skier(m) = 60 kg

height of the slope(h) = 10m/s

Speed(v) = 10m/s

By conservation of Energy states the law of conservation of energy states that the total energy of an isolated system remains constant.

P.E(Potential Energy) = mgh

K.E(Kinetic Energy)=

E represents the energy lose due to friction.

then;

Substitute the given values;

Use

then;

Simplify:

or

Therefore, the energy does she lose to friction is 2880 joule

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
