Homework Statement A cylindrical drum of molasses is 25% full and laying on its side. The dimension sof the drum are 4 ft. height and 1.5 ft. radius. Find the pressure on the circular side (end) of the drum) created by the molasses. Weight density of molasses = 100 lb/ft^3 Homework...

Okay, I think I have them both now. Thank you so much!

Yes! So I can find the potential energy at the top of the hill, set that equal to 1/2mv^2, and just solve for v? How do I factor the first hill into that, though?

For the first problem, I know how to find the potential energy at either of the hills, but I'm unsure of how exactly to use this knowledge to find velocity. Or, could I find the velocity at the bottom of the first hill, and then find out how much it decelerates as it climbs the second?

Hello! I was hoping somebody could help me with these two problems: A roller-coaster has a first hill 75.2 meters tall. Immediately after this hill, the roller coaster skims along the ground, then ascends to a second hill 47.8 m tall. If the load limit is 1067.9 kg, how fast is it going at...
