MCQ
A ball thrown vertically upward is in free flight (air resistance ignored). Its acceleration at all points of the journey is:
Unit-2 Kinematics
A zero at the highest point
B 9.8 m/s^2 directed downward
C 9.8 m/s^2 directed upward
D equal to the ball's speed
Explanation

In free flight under gravity the acceleration is always g = 9.8 m/s^2 downward, even at the highest point where speed is zero.
