Particle Models in Two Dimensions Worksheet 2: Horizontally Launched Projectiles 1. Given the following situation of a marble in motion on a rail with negligible Ffriction: a. Sketch a velocity motion map showing the motion of the marble after it leaves the rail, using the grid to help you carefully locate the marble's positions. Show both horizontal and vertical velocity vectors on each dot. V = 10. m/s h = 1.5 m b. Once the ball leaves the table, calculate how long it will take for the ball to hit the floor. C 0.55 s 1 travel horizontally before
