at the top: force on scale=mg -mv^2/r
at the bottom: forceonscal=mg+mv^2/r
The 56 kg man in the roller coaster car is sitting on a bathroom scale. If he is traveling at 40.9 m/s at the point shown and the radius of the vertical coaster track is 87 meters, to the nearest newton what does the scale read? What is the answer to the previous problem if the roller coaster is at the bottom of the track?
I don't know where to even begin for this problem. The only equation I can think of is a(c) = v^2/r but I don't know how to use it/how to apply it to this problem. Please help! Thank you!
