On level ground, a shell is fired with an initial velocity of 35.0 m/s at 60.0° above the horizontal and feels no appreciable air resistance.

a. How much time is required for the shell to reach the highest point of the trajectory?
b. How high is this point?
c. How much time (after it is thrown) is required for the shell to return to its original level?
d. How does this compare with the time calculated in part (a)?
e. How far has it traveled horizontally during this time?
