Problem

A block of mass

0.20\,\text{kg}

is released from rest at a height

H

above the bottom of a frictionless circular loop-the-loop track of radius

4.0\,\text{m}

. Determine the minimum value of

H

that will allow the block to maintain contact with the track all the way around the loop. Assume

g = 9.8\,\text{m}\,/\,\text{s}^2

and express

H

in meters.
