A cue ball smacks into the 8-ball, but alas you scratch and lose the game. Which is true about an impact?“a) The coefficient of restitution between the cue ball and 8-ball is probably just above zerob) The combined linear momentum of the two balls is the same before and after the impact.c) The linear momentum of the cue ball is the conserved through the impactd) Mechanical energy before the impact is the same as the mechanical energy after the impact.
Look at Problem 3.143. To solve this, you will need:a)to determine the normal force over the motion of the collar.b) to find the work done by the force by the total displacement of the cord (ie, how much cord is "pulled out")a)to calculate the total distance along the slider between C and Db)to know the coefficient of restitution when the collar hits BReleased from rest at A, smooth collar, constant force F that will make the collar hit B with a velocity of 4 m/s
QUIZ1. The velocity of B relative to A is defined as
vB .
vB .2. Since vector addition forms a triangle, there can be at most _________ unknowns (either magnitudes and/or directions of the vectors).
