PLEASE ANSWER ALL QUESTION WHICH ONE IS MISSING. THANK YOU SO MUCH. ロvelocity vs. nme Graph A ball is thrown straight up into the air and then, on the way back down, is caught at the same height it was released at. For the following graphs, UP IS POSITIVE & DOWN IS NEGATIVE. Assume there is no air drag. Which one of the following vy vs. t graphs best represents the motion of the ball the entire time it was...
8. A student rolls a marble alongside a meterstick to measure its velocity. At t1 = -2.5 s, its position is x1 = 4.3 cm, and at t2 = 4.5 s it is at x2 = 18.5 cm. Determine its average velocity during this time interval. 9. The position of a ball rolling along a straight line is given by ? = 1.8−3.6? +1.5?2, where x is in meters and t is in seconds. Determine the average velocity of the...

A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...
