If the package of Prob. 13.74 is not to hit the horizontal surface at C with a speed greater than 3.5 m/s, (a) show that this requirement can be satisfied only by the second loop, (b) determine the largest allowable initial velocity v0 when the second loop is used.
Prob. 13.74 A 200-g package is projected upward with a velocity
0 by a spring at A; it moves around a frictionless loop and is deposited at C. For each of the two loops shown, determine (a) the smallest velocity v0 for which the package will reach C, (b) the corresponding force exerted by the package on the loop just before the package leaves the loop at C
