т Your bow can fire arrows at 704. You shoot an arrow straight up into the air. After 1 second, you shoot another arrow into the air. a) If you are shooting the arrows from 2 m above the ground, how far above the ground do the arrows collide? (Answer: 251 m) -4.99 vg = 4.99) b) What are the velocities of the arrows when they collide? (Answer: 74 : c) On a single graph, plot y-position vs time for each arrow. This should show the intersection of where and when they collide.
