A potato is fired from the top of a 125m tall cliff with an initial speed of 65.0m/s at an angle of 37 degrees about the horizontal. It flies through the air and travels a horizontal distance of "X" before hitting the ground at point "P" 
a) find the x and y components of the potato's initial velocity (I know this is x=51.91 m/s and y=39.12m/s) 
b) find the total time the projectile spends in the air before hitting the ground 
c) find the horizontal distance, X, that the potato travels before hitting the ground 
d) find the projectile'a velocity (magnitude and direction) right before it hits the ground, at point P.
