Answer:
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
Answer:
25.5
Step-by-step explanation:
first find the area od the rectangle than the triangle.
to find the area count the number of squares and use A=b*h
than do the same for the triangle using A=.5*b*h
15=3*5
10.5=.5*3*7
10.5+15=25.5
