[DOCUMENT TITLE] | Flip PageName: _____________(20 points)Comprehension Check (3): Free Fall &Graphs1.An object is thrown straight up with an initial velocity v0. The graphrepresents the object’s vertical displacement as a function of time. Atwhat time does the object reach its maximum height? (1 pt)A. 2 s B. 4 s C. 6 s D. 10 s E. 5 s2.Two balls are thrown from a cliff with the same initial speed, one is thrown up, and theother is down. Compare the speeds of the baseballs just before they hit the ground. (1pt)A. The one thrown up moves faster because the initial velocity is upB. The one thrown down moves faster because the initial velocity is downC. They both move with the same speedD. The one thrown up moves faster because it has greater accelerationE. The one thrown down moves faster because it has greater acceleration3.The graph to the right describes the relationship between velocity and time for a moving object. A) What is the total displacement for the entire trip?(2 pts)B) What is the acceleration of the object from 5-7 seconds? What is theacceleration of the object at 7-9 seconds?(2 pts)4.Match the following graphs that go together (4 pts)PositionVelocityAccelerationi) Ai)i)ii)Bii)ii)iii) Ciii)iii)iiii) Diiii)iiii)
[DOCUMENT TITLE] | Flip Page5.A stone is dropped from the roof of a building. It took 5 s for the stone to reach the ground. What is the height of the building? (3 pts)6.A man is on a 30m cliff and throws a ball down with a speed of 7 m/s.A) With what velocity does the ball hit the ground?(2 pts)B) How high above the ground is the ball after the ball has fallen for 1 second?(2 pts)C) If a second ball is dropped the same time as the first ball is thrown down, how high above the ground will the second ball be the moment the first ball hits the ground? (2 pts)7.[Honors]A ball is thrown straight up into the air and passes a window 3 seconds after being released. It passes the same window on its way back down 1.5 seconds later. What was the initial velocity of the ball? (3 pts)
