11) A projectile is fired with an initial velocity of 120.0 m/s at an angle, θ, above the horizontal. If the projectile's initial horizontal speed is 55 meters per second, then angle θ measures approximately (A) 13° (B) 27° (C) 63° (D) 75° 12) A golf ball is hit at an angle of 45° above the horizontal.
The projectile is fired with a velocity of magnitude 90m/s at angle 45 degree to the horizontal. We can divide the initial velocity into a horizontal component of 90 sin 45 = 90/sqrt 2 and a ...
