Homework Help: Physics

Posted by Jenny on Monday, October 1, 2007 at 3:50pm.

For a question in physics... I was told to draw a graph of vertical displacement, y, versus time, t, in 2sec increments from 0 to 1.8. What was given to me was:

v_yo_= +10m/s
v_xo_= +5m/s
a_y_ = -10m/s^2

So I used the formula: y=vo+1/2at^2
I drew the graph, and got a parabala.

Now, my question is, how do I find instantaneous vertical velocity at 6s using the graph?

Do I use the linear question for horizontal motion at all in this problem? x=vo(t)

Any help would be great. THanks
