Question

A player kicks a soccer ball in a high arc toward the opponent's goal. At the highest point in its trajectory

Answer 1

At the highest point in its trajectory, the ball's acceleration is zero but its velocity is not zero.

What's the velocity of the ball at the highest point of the trajectory?

• At the highest point, the ball doesn't go more high. So its vertical velocity is zero.
• However, the ball moves horizontal, so its horizontal component of velocity is non - zero i.e. u×cosθ.
• u= initial velocity, θ= angle of projection

What's the acceleration of the ball at the highest point of projectile?

• During the whole projectile motion, the earth exerts the gravitational force with a acceleration of gravity along vertical direction.
• But as there's no acceleration along vertical direction, so the acceleration along vertical direction is zero.

Thus, we can conclude that the acceleration is zero and velocity is non-zero at the highest point projectile motion.
