ok thanks a lot

what did you receive for time? 7m/s is initial velocity right?

it is d(m) vs t(s)...so it is distance versus time

How do you find average velocity by reading off of a data graph?

thank you so much, i got it. except i made Vo=32t instead. :D

thanks but I'm still stucki got Vo^2=12800/-15 and you can't do a square root of a negative :S

A ball thrown straigh upward from the ground reaches a maximum height of 400ft. What was its initial velocity? Using the formulas: V=at+Vo X=1/2at^2+Vot+Xo the distance traveled is 400ft, and the initial distance was 0. The force of gravity is -32ft/s/s. Also, the velocity of the ball at the...
