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?
Homework Answers
Radius = 12 inch
= 0.3048 m
Velocity at lowest point = √5gr
= √ (5× 9.81 × 0.3048)
= 3.86 m/s

Consider a solid sphere of mass m and radius r being released
from a height h (i.e., its center of mass is initially a height h
above the ground). It rolls without slipping and passes through a
vertical loop of radius R.
a. Use energy conservation to determine the tangential and
angular velocities of the sphere when it reaches the top of the
loop.

h 2R A block starts at the top of a frictionless track at some height h. It is released so that it slides down the track and toward a vertical loop of radius R = 1m. In order to clear the hoop, what is the lowest height h that the block can be dropped from? Hint 1: This combines both energy and forces. Think about the difference in height too. Hint 2: Think about what it means to clear the...
