Question
A sphere is accelerated upward by a cord whose breaking strength is four times its weight. The maximum acceleration with which the sphere can move up without breaking the cord is(a) $g$(b) $3 \mathrm{~g}$(c) $2 \mathrm{~g}$(d) $4 \mathrm{~g}$
Step 1
The breaking strength of the cord is four times the weight of the sphere. The weight of the sphere is given by W = mg, where m is the mass of the sphere and g is the acceleration due to gravity. So, the breaking strength of the cord is 4mg. Show more…

A 23.1-kg sphere $A$ of radius $90 \mathrm{~mm}$ moving with a velocity of magnitude $v_{0}=2 \mathrm{~m} / \mathrm{s}$ strikes a $2.1-\mathrm{kg}$ sphere $B$ of radius $40 \mathrm{~mm}$ that is hanging from an inextensible cord and is initially at rest. Knowing that sphere $B$ swings to a maximum height $h=0.25 \mathrm{~m}$, determine the coefficient of restitution between the two spheres.

Impacts
Three spheres, each with a mass of $m,$ can slide freely on a frictionless, horizontal surface. Spheres $A$ and $B$ are attached to an inextensible, inelastic cord with a length $l$ and are at rest in the position shown when sphere $B$ is struck squarely by sphere $C,$ which is moving with a velocity $v_{0}$. Knowing that the cord is taut when sphere $B$ is struck by sphere $C$ and assuming perfectly elastic impact between $B$ and $C,$ and thus the conservation of energy for the entire system, determine the velocity of each sphere immediately after impact.
