Friction Problem. Help!
Homework Statement
In the absence of friction, we know v = (2gd)^(1/2). But with a correction factor that accounts for friction what would be the modified farmula?

Is this the vector diagram i am going to make http://docs.google.com/Doc?id=dctgg53g_60dsdbbn

Homework Statement
After flying for 15 min in a wind blowing 42 km/h at an angle of 18° south of east, an airplane pilot is over a town that is 60 km due north of the starting point. What is the speed of the airplane relative to the air?

Because at the end of the interval Instantaneous velocity is on the peak and AVG velocity is the averages of the inital + final. (i am not sure):confused:
OK one thing i got here:
SECTION I
Coloumn comparison "Velocity" vs yi/ti
"Velocity" = Instantaneous Velocity
yi/ti = Average Velocity
Conclusion: In a free falling body, when we take equal time intervals and unequal displacements. Avg Velocity is half of Instantaneous velocity...
Q1.
Average Acceleration = delta x/ delta ok i understand
but what is yi/ti^2?
WHY yi/ti^2 is half of avg acceleration?
WHats the logic comming out of it?
Free fall Experiment Help!
1. Homework Statement
Experiment:-
OBJECTIVES
In this experiment you will investigate the motion of a freely falling body on a fictitious planet.
You will discover for an object that falls from rest
(1) the value of the acceleration due to gravity on the...
OK I think i am getting what you guys are saying:
when we throw something in upward direction we can use either of these equations
-s=-ut+1/2gt^2 or
s=ut-1/2gt^2
Am i right!
