Xo=0 X 3-8 Solving Problems involving Projectile Motion Example 3-10: Level horizontal range. (a) Derive a formula for the y = 0 again here horizontal range R of a projectile in yo = 0 (where x =R) terms of its initial speed v, and angle ©. The horizontal range is defined as the horizontal distance the projectile travels before returning to its original height (which is typically the ground); that is, y(final) = yo. (b) Suppose one of Napoleon's cannons had a muzzle speed, vo, of 60.0 m/s. At what angle should it have been aimed (ignore air resistance) to strike a target 320 m away? R 60° 30° 35 en )
