INTERACTIVE LECTURE DEMONSTRATION PREDICTION SHEET-PROJECTILE MOTION Directions: This sheet will be collected. Write your name at the top to record your presence write and participation in these demonstrations. Follow your instructor's directions. You may whatever you wish on the attached Results Sheet and take it with you. +y Today's physical demonstration involves a ball thrown in the air with an initial velocity upward and to the right. The trajectory of the ball looks approximately like the sketch to the right. Note that the origin of the coordinate system has been chosen to be the initial position of the ball. 0

Problem 7: Use the position vs. time graph shown in figure to the right to answer the following questions. On the plot, the x-intervals are Ax = 1 m and the time intervals are At = 13 s. Ax+ Δι

Based on the diagram below, what is the initial velocity of the object if it takes 7.301s to go from position A to position B and it accelerates at a constant -2.274m/s2.  The distance between A/B is shown below.  Everything in this problem is happening vertically.
