Questions & Step-by-Step Solutions
A ball is thrown at an angle of 45 degrees with an initial speed of 28 m/s. What is the vertical component of the velocity at the peak of its trajectory?
Step 1: Understand that when a ball is thrown at an angle, it has two components of velocity: vertical (up and down) and horizontal (side to side).
Step 2: Recognize that at the peak of the ball's trajectory (the highest point), the vertical component of the velocity becomes 0 m/s because the ball stops moving upward and is about to start falling down.
Step 3: Conclude that regardless of the initial speed or angle, at the peak, the vertical component of the velocity is always 0 m/s.
Projectile Motion – Understanding the behavior of objects thrown into the air, including the effects of gravity on vertical and horizontal components of velocity.
Velocity Components – Breaking down the initial velocity into horizontal and vertical components using trigonometric functions.
Peak of Trajectory – Recognizing that at the highest point of a projectile's path, the vertical component of velocity is zero.
