I simplified the circuit down to equivalent values. Sorry for the poor image of the...
Thanks for the help obafgkmrns. You really made me see how I can easily get confused on such a simple thing.
It's hard for me to figure out how to analyze problems like this and derive the right formulas cause I'm not that great at physics. And it doesn't help that my professor is a bit...
Homework Statement
An ice cube is given a push at the top of an incline giving it an initial speed of 7 m/s down the incline. At the bottom of the incline the ice cube is deflected vertically upward as shown in the accompanying diagram. Ignoring friction and air resistance, how high H does...
Thanks for the reply. I see what I did wrong now.
So I converted the 1/4 mile to 402.34 meters.
I found the final velocity of the first segment using
v^2 = v_0^2 + 2 a \Delta x
.
The final velocity was 100 m/s for the first segment.
100 m/s is the initial velocity for the...
