Energy transfer is the changing of the form of energy. In this example, the form of energy changed from chemical, to kinetic, to gravitational, to then sound and internal energy.

a car travels at 50 m/s for first 20 seconds , 30 m/s for next 30 seconds and finally 20 m/s for next 10 seconds . find its aver

kaheart [24]

The average speed traveled by car is $35m/s$ .

$1^{st}$ case

Speed $=50m/s\\$

Time $=20s$

Distance $=$ $speed*time= 50*20=1000m$

$2^{nd}$ case

Speed $=30m/s$
Time $=30s$

Distance $=30*30=900m$

$3^{rd}$ case

Speed $=20m/s$
Time $=10s$

Distance $=20*10=200m$

Now, The total distance $=(1000+900+200)m=2100m$

Total time $=(20+30+10)s=60s$

Average distance $=\frac{total distance}{total time} = \frac{2100}{60}=35m/s$

Thank you for posting your question here at brainly. Below is the solution:

Ke up top = 1/2*.25 *225
gain of Pot energy = .25*9.81*1.2 
work input = (1/4)(2 pi *.6)*30 

so 
sum of those 3 energies = 
(1/2)(.25)v^2
