5. An arrow of mass 40.0 g and initial speed of 150 m/s is fired into a bullseye target stand with mass 0.105kg. You shoot the arrow so hard that it passes right through the target. The target stand is resting on a frictionless surface. Immediately after the arrow exits the stand, the speed of the target stand is 23 m/s. (a) What is the speed of the arrow when it exits the target stand? (b) Calculate the initial and final kinetic energies of the system and the percent change Sketch and Label Define the coordinate axis.
