Challenge Exercise: A projectile-buoy target lies 100 m away. Determine at least one possible set of values for V0 and θ in Figure 2.6 such that a 5-kg projectile hits the target. How much energy must the Lyle gun impart to the projectile in order to meet this objective? (Hint: When the buoy first leaves the muzzle, its kinetic energy is )
