Question
Your bow can fire arrows at 70 ?
?
. 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)
Expert Solution
Step 1
Here, the second arrow is fired 1 second from the first arrow. So, consider first arrow fired at t=0 s, then the second arrow fired at t=1 s.
So, using kinematic equation, the position of first arrow at time t is,
Here, is the initial velocity of first arrow, is its acceleration.
