1. Car A and Car B are 576 [m] apart and are at rest. At the same time, Car A accelerates to the right at 3.00 [m/s2] and Car B accelerates to the left at 5.00 [m/s2]. How far will Car B have to travel to collide with Car A? A. 30.0 m B. 180.0 (m) C. 60.0 (m) D. 360.0 [m] 2. Gru's position coordinates were locked at (x, y, z) = (15,-3, 10) [m] from Vector's current position. What is the distance and bearing between Gru and Vector at that very moment? Assume Vector is at the origin of a coordinate axis, and the bearing angle is measured on the x-y plane from the +x-axis. A. 17.78 (m), 11.31° B. 17.78 [m] -11.31 C. 18.28 [m], -11.31 D. 18.28 [m]. 11.31 3. An object moves with a velocity that changes uniformly from t = 0 to t = T. Which of the following is TRUE about the magnitudes of its instantaneous acceleration a at t = T and average acceleration aave in the interval t = 0 and t = T? A. lal > Cave B. lal <laavel C. lal = leave D. lal = 3|dave 4. Penn and Teller decided to do a magic trick involving a coin and a baseball. Penn throws the baseball straight upwards from the ground with an initial velocity of vo,ball = 5 [m/s] j At the exact moment that the baseball was released, Teller throws the coin with an initial velocity of vo,coin = 10 [m/s]"i + 5 [m/s] j from the ground. Which of the following is true about the two objects? A. The baseball will reach the ground first. B. The coin will reach a greater height. C. Both objects will reach the ground at the same time. D.
