Approach Analysis
Consider the fundamental aspects of projectile motion: along the horizontal (x) direction, there is no horizontal acceleration (assuming air resistance is negligible), so the horizontal velocity remains constant; along the vertical (y) direction, there is a constant downward acceleration due to gravity, so the vertical velocity changes over time.
Option a: 'In the x directi......Login to view full explanationLog in for full answers

What is projectile motion?
Question at position 2 Question: In this lab, which equipment, methods, or physical principles will you use to deduce the ball's launch velocity? Select all true statements. I will use a ballistic pendulum and principles of momentum and energy.I will use a photogate and approximate the velocity with constant-velocity kinematics.I will use a ruler to measure the ball's impact distance into the pendulum's catcher and principles of inelastic collisions.I will use a meter stick to measure the ball's range and assume projectile motion models the ball's free-flight motion.I will use a caliper to measure the spring launcher's compression and the concept of elastic potential energy.I will use a motion sensor to measure the ball's launch velocity directly.None of the above statements are true.
