Question

It takes t seconds for a projectile to complete its trajectory. How much time has passed when the projectile reaches the highest point in its trajectory?

A) t
B) ¼ t
C) ½ t
D) ¾ t

Answer 1

The time elapsed when a projectile reaches the highest point of its trajectory is half the total time of flight, so the answer is C) ½ t.

Step-by-step explanation:

When a projectile reaches the highest point in its trajectory, half the total time of flight has passed. This occurs because the ascent time to the highest point is equal to the descent time from that point to the ground, assuming the projectile does not encounter any significant resistance, like air resistance, and lands at the same elevation from which it was launched. The correct answer is therefore C) ½ t.
