Problem 8: A cue ball of mass m - 4325 kg is shot at another billiard ball with mass mz - 4.595 kg, which is at rest. The cue ball has an initial speed of v- &m's in the positive direction. Assume that the collision is elastic and exactly head-on, Part (a) Write an expression for the horizontal component of the billiard ball's velocity, v2f, after the collision, in terms of the other variables of the problem. Expression: v2f_____________ Select from the variables below to write your expression. Note that all variables may not be required. a, b, 0, a, d, g, h, j, k, m, mı, m2, P, t, v Part (b) What is this velocity, in meters per second? Numeric : A numeric value is expected and not an expression. v2f____________________
Part (c) Write an expression for the horizontal component of the cue ball's velocity, vif after the collision Expression: V1F__________ Select from the variables below to write your expression. Note that all variables may not be required. a, B, 0, a, d, g, h, j, k, m, m, m2, P, T, v Part (d) What is the horizontal component of the cue ball's final velocity, in meters per second? Numeric : A numeric value is expected and not an expression. v1f____________________
