1. A projectile is launched at an angle of 300 above the horizontal. Neglecting air resistance, what are the projectile's horizontal and vertical accelerations when it reaches its naximum height? [a] Both the horizontal and vertical accelerations are zero. Cb] The horizontal acceleration is zero and the vertical acceleration is 9.81 m/s2. Sad! [c] The horizontal acceleration is 9.81 m/s2 and the vertical acceleration is zero. Both the horizontal and vertical accelerations are 9.81 m/s2.
