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

Step 1
Step 1: At the highest point in the trajectory, the vertical component of the velocity becomes zero because the ball no longer has any vertical displacement. Show more…

At the maximum height of a projectile launched upwards from ground at an angle with horizontal, (a) velocity is zero but acceleration is not zero (b) velocity and acceleration both are zero (c) vertical component of velocity is zero, but acceleration is not zero (d) vertical component of velocity as well as acceleration are zero
A player throws a ball vertically upwards with velocity $u$. At highest point (a) both the velocity and acceleration of the ball are zero. (b) the velocity of the ball is $u$ but its Ă cceleration is zero. (c) the velocity of the ball is zero but its acceleration is $g$ - (d) the velocity of the ball is $u$ but its acceleration is $g$.
A ball is thrown downwards from the edge of a very high cliff with an initial speed that is greater than the terminal speed. Mark the correct statement about its acceleration a. It is always acting in the upward direction b. It is always acting in the downward direction c. Initially, it is acting in upward direction and then it becomes zero d. Initially, it is acting in upward direction and then it attains a non-zero constant value in the downward direction
