Correct option is D
The correct answer is: (d) 9.81 m/s² acting downward
Explanation:
When a body is thrown vertically upward, it moves against gravity and gradually slows down due to the constant acceleration caused by gravity.
When a body is thrown vertically upward, it moves against gravity and gradually slows down due to the constant acceleration caused by gravity.
This acceleration remains constant throughout the motion — during ascent, at the highest point, and during descent.
Information Booster:
Upward journey: Velocity decreases due to negative acceleration (opposing motion).
At the highest point, velocity is 0 m/s, but acceleration is not zero.
The body immediately begins to accelerate downward after reaching the highest point.
The motion is symmetric: time taken to rise = time taken to fall.
The net force acting on the object is its weight, i.e., mass × gravity.
Upward journey: Velocity decreases due to negative acceleration (opposing motion).
