NEET Physics Projectile Motion Assertion Reason Question
Assertion (A): The time of flight of a projectile is twice the time taken to reach its maximum height. | Reason (R): The vertical component of velocity becomes zero at maximum height, and the total time of flight is determined by the initial vertical velocity component and the acceleration due to gravity.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
According to the NCERT context, the time of flight T_f = 2(v_o sin θ_o)/g is twice the time to reach maximum height, t_m = (v_o sin θ_o)/g, due to the symmetry in projectile motion.
