Question:

The 2-lbm mass m is released down a frictionless track from a height h. If the loop at the bottom has radius 12 inches, what is the minimum h from which the mass can be released so it will go around the loop?


Answers

Radius = 12 inch

= 0.3048 m

Velocity at lowest point = √5gr

= √ (5× 9.81 × 0.3048)

= 3.86 m/s
