when something is at its Max height (projectile motion), what is the direction of it's velocity? I know the velocity will be the velocity of the x component (since the y component would be 0), but I'm not sure how to find the angle.

2. For a projectile launched with an upward initial velocity, the horizontal velocity is always and the vertical velocityHint: Pretend the initial vertical velocity is 3m/s and the initial horizontal velocity is 2 m/s. How do these numbers change as the projectile approaches the peak and then approaches landing? a) Constant, Decreases then Increases b) Zero, Is Lowest at the Apex c) Constant, Always Decreases d) Positive, Decreases then Increases

47. An object undergoing projectile motion travels 1.00 x 102 m in the horizontal direction before returning to its initial height. If the object is thrown initially at a 30.0° angle from the horizontal, determine the x component and the y component of the initial velocity. (Neglect any effects due to air resistance.) Example 3-7

PROJECTILE MOTION OBJECTIVE: The purpose of this lab is to study the properties of projectile motion. From the motion of a steel ball projected horizontally, the initial velocity of the ball ean be determined from the measured range. For a given initial velocity, the projectile range will be measured for various initial angles, and calculated by applying the theory for motion with constant acceleration BASIC PRINCIPLES: Projectile motion occurs when an object in a two-dimensional plane experiences motion only due...
