If a cart rolled down a ramp 5 meters high and flew off a a table at 3 meters high, what would its velocity be?
please let me know where i go wrong, i was using the law of conservation of energy
mgh1=mgh2+1/2mv2
mg(h1-h2)=1/2mv2
v=square root of 2g(h1-h2)
where h1=5 and h2=3
i plugged in...
Hi guys.
I need a few equations to complete a table.
I am given numbers for:
Fg (N)
h (m)
Fa (N)
d(m)
and I need to find:
Work Output (J)
Work Input (J)
Effeciency
If anyone has those three equations I could use it would be greatly appreciated.
