2. 2D Motion Suppose a projectile is fired at to = 0 with initial speed vo and angle o above the horizontal. a) (5 points) Sketch the physical situation and label

your sketch with appropriate quantities from the problem statement. Choose an appropriate coordinate system. Make a table of known/given information and unknown/wanted information (this may involve reading the rest of the problem before starting). List any physical assumptions you will be making to solve the problem. b) (5 points) Find a purely symbolic algebraic expression which will predict the total time the projectile is in the air for any initial speed vo and angle 00. c) (5 points) Find a purely symbolic algebraic expression for the magnitude of the projectile's velocity (impact speed) as a function of time (at any future time t) for any initial speed vo and angle 00.
