A rock is thrown upward from a bridge at an initial height of 8 meters
above the water at an initial speed of v1 and an angle of 37 degree
from the vertical as shown. Use g=10 m/s^2 to solve this problem.
a) Write a set of equations for the horizontal and vertical positions and
velocities of the rock as a function of time. Clearly indicate on your
drawing your choice of axes and what point you are using as your origin.
b) The rock reaches its highest point in 2 seconds. How high is
the rock above the water at that instant? (First you need to find v1
