Homework Help: Physics(Please respond)

Posted by Hannah on Wednesday, May 30, 2012 at 9:17pm.

a rollar coaster is 80m high and has a 50kg car at rest. Ignore air resistance and friction.

If the speed of the car is 60m/s what is the height?

0+50(9.8)(80) = 1/2(50)(vf^2) + (60)^2 + 50(9.8)(h).

Is this equation correct?? If so I do not know how to solve for h since on the right side there is the h and vf^2.
