A small ball of mass m1=0.84kg and initial speed v1=18.2m/s makes a collision with another ball of mass m2 =1.4kg which is initially at rest on a frictionless horizontal table. After the collision the balls move as shown in the figure. Given θ=240, determine the speed of m2 just after the collision, that is, v2'=? Express your answer using one decimal place.
