if we sum the forces in the normal direction wouldn't it be: mg- N= m (50)^2/ 668.04 ??

Nope! Want to help me? :)

You'd have to make some conversions because velocity is in seconds. So 100 mi/h= 146.6 ft/s then p= 146.6 ^2/ 32.2 Correct? Thank you so much!

During a high-speed chase, a 2400-lb sports car traveling at a speed of 100 mi/h just loses contact with the road as it reaches the crest A of a hill. a) Determine the radius of curvature r of the vertical profile of the road at A. b) Using the value of r found in a part a), determine the...
