Your friend is trapped in a castle tower. You want to send her a message by attaching it to an arrow and shooting the arrow into a window in the tower. The angle of the arrow when it leaves the bow is 40o measured from the horizontal, and its initial velocity is 90 m/s. You are 80 meter from the tower, and you can neglect your height.
a. Determine the x and y components of the arrows initial velocity?
b. Determine how long does it take for the arrow to reach the window in the tower?
c. Determine how high above the ground is the window?
