A projectile is launched at an initial angle of 50o with a speed of vo = 15 m/s from the top of a hill 5 meters above level ground.
a) What is the projectile's height above the surface at this time?
b) How long does it take, from the instant of firing, for the projectile to hit the ground? What condition do you impose on the y equations to find this time?
c) Find the range of the projectile from launch to impact.
d) Find the x and y components of the velocity of the projectile as it strikes the ground.
e) What is the magnitude of the velocity of the projectile when it strikes the ground?
f) Make a sketch of the trajectory labeling the times and positions of the projectile at launch, peak, and impact point.
