Correct option is C
The correct answer is option (c) 0.
Explanation
When an object is thrown vertically upward, it slows down due to the force of gravity acting against its motion. At the highest point of the object's trajectory, its upward velocity becomes zero for an instant before it starts to fall back down. This is because, at that point, the object momentarily stops before gravity pulls it downward.
Information Booster
The velocity of the object at the highest point is zero, but the acceleration due to gravity is still acting on the object, pulling it downward.
At the highest point, the object’s kinetic energy is at its lowest, and the potential energy is at its maximum.
The time to reach the highest point depends on the initial speed and the acceleration due to gravity, but at the highest point, the speed becomes zero before it reverses direction.
