Question

A ball is thrown into the air and follows a parabolic trajectory. At the highest point in the trajectory (A) the velocity is zero, but the acceleration is not zero (B) both the velocity and the acceleration are zero (C) the acceleration is zero, but the velocity is not zero (D) neither the acceleration nor the velocity are zero

At highest point, speed is not zero and acceleration is g downward. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-uvw1zryzhelv0bjy.jpg" />

Q. A ball is thrown into the air and follows a parabolic trajectory. At the highest point in the trajectory

the velocity is zero, but the acceleration is not zero

both the velocity and the acceleration are zero

the acceleration is zero, but the velocity is not zero

neither the acceleration nor the velocity are zero

At highest point, speed is not zero and acceleration is g downward.
