Answer:

The mechanical energy is not conserved

Step-by-step explanation:

Recall that the law of conservation of energy states that in an isolated system (no external forces acting on it), the mechanical energy is conserved.

A skier skiing down a slope is not an isolated system in this case because the friction of the snow causes some of the mechanical energy to convert to thermal energy.

rodikova [14]

Answer:

B

Step-by-step explanation:

We can use the law of cosinse:

$c^{2}$ = $a^{2} + b^{2}$ − 2ab cos(C)

Suppose the two sides are a and b, and the angle betweent them is C.

$c^{2}$ = $3^{2} + 4^{2}$ − 2*3*4 cos(60)

We can simplify this to get $c^{2}$ =25-12=13

c= $\sqrt{13}$
