Horizontal Displacement (m) +9.8 --9.8 -9.8 -9.8 D) -9.8 -9.8 4. Our equations of motions for projectiles assume: A) the start point is x = 0 m and y = 0 m. B) the horizontal velocity is a constant. C) there is no friction due to air resistance. D) All of the above. %3D %3D 5. The diagram at the right shows the trajectory of three artillery shells. Each was fired with the same initial speed. Which shell was in the air for the longest time? (Ignore air friction.) A C) Shell C. A) Shell A. D) Shells A and C were in the air for equal time, which was longer than for shell B. B) Shell B. 6. A projectile is fired into the air at some angle above the horizontal. The horizontal displacement of the projectile is measured against time in flight and the collected data is shown as a horizontal displacement versus time graph at the right. Based on this graph, the horizontal velocity of the projectile during this time interval is: A) constant. C) decreasing. B) increasing. D) equal to zero. draw the graph of Horizontal Displac
