hope this helps:)sorry if it doesnt
the answer is true like and sub to zeelitmotion :
The pilot makes a big triangle with her flight path. The longest side will be her distance from the start as the crow flies.
Use the Law of Cosines (deg mode on a calculator):
c^2 = a^2 + b^2 - 2ab(cos C)
C = 170 degrees (only a 10 deg correction from 180)
a = 685 x 1.5 = 1027.5 miles
b = 685 x 2 = 1370 miles
It doesn’t matter which side is a and which side is b.
Now plug in the values and solve for c. Hope this helps.
Answer:
some of the energy is transformed to thermal energy
According to the position vs time graph, the <em>average</em> <em>velocity</em> of the motorcycle is the change in position divided by the change in time. Also, note that the slope is linear and positive throughout the 5 hours, it doesn't change direction.
Therefore, we have
Avg velocity = change in direction/change in time
Avg velocity = (150km - 30km)/(5h - 0h)
Avg velocity = 24km/hr south.
