Sphere A has a weight of $37lb$ and a radius of $7in.,$ while sphere $B$ has a weight of $7lb$ and a radius of $5$

in$.$ If the spheres are traveling initially along the parallel paths with the speeds shown, determine the

velocities of the spheres immediately after impact. Specify the angles ${}_A$ and ${}_B$ with respect to the $x-$

axis made by the rebound velocity vectors. The coefficient of restitution is $0\mathrm{.}55$ and friction is

neglected. Enter positive numbers for the angles $.$

Answers:

$v_A=$

$f\frac{t}{sec,{}_A}=$

$v_B=$

$f\frac{t}{sec,{}_B}=$
