Assignment Gradebook ORION Downloadable eTextbook ent MESSAGE MY INSTRUCTOR FULL SCREEN PRINTER VERSION ·BACK NEXT Chapter 09, Problem 054 A completely inelastic collision occurs between two balls of wet putty that move directly toward each other along a vertical axis. Just before the collision, one ball, of mass 3.3 kg, is moving upward at 20 m/s and the other ball, of mass 1.5 kg, is moving downward at 13 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.)

let
m1 = 3.3 kg, v1 = 20 m/s
m2 = 1.5 kg, v2 = -13 m/s
Apply conservation of momentum
let v is the velocity of both object just after sticking.
Apply conservation of momentum
m1*v1 + m2*v2 = (m1 + m2)*v
3.3*20 + 1.5*(-13) = (3.3 + 1.5)*v
==> v = (3.3*20 + 1.5*(-13))/(3.3 + 1.5)
= 9.6875 m/s
maximum height reached above the collsion point,
h_max = v^2/(2*g)
= 9.6875^2/(2*9.8)
= 4.80 m <<<<<<<<<=================Answer
