5. A 0.8 kg apple is balanced on a circus performer's head 1.9 m above the ground. An archer shoots a 50 g arrow at the apple with a speed of 45 m/s. The arrow passes through the apple and emerges with a speed of 12 m/s. m=0.050 V=45 m2=0.8 V2=0 V'=45 BEFORE Collision AFTER Collision Ay=1.9m Ax=? Projectile Motion of Apple a. Write the momentum conservation equation in terms of variables (m,v). b. Find the speed of the apple as it flies off the performer's head. c. What is the impulse exerted on the apple by the arrow? d. What is the impulse exerted on the arrow by the apple?
