m: Assume air resistance can be neglected in the questions that follow. Remember to include a sign convention for each question. Also make sure that for each question you include a clearly labeled (i.e. with given information noted) and appropriately-sized diagram Tiny little diagrams without numerical labeling will not receive any credit. Each diagram is worth 1 point, so please don 't forget to include them! Your sign convention must also be presented with each question and is also worth I point. 1, You watch as your roommate throws a small ball vertically upward with a speed of A) How long does it take for the ball to reach the highest point in its path? B) How high does the ball rise (above its release point)? C) What is the velocity of the ball after 4.07 s have elapsed? (11 points) 2. A vehicle travels along a certain road at an average speed of 6 and returns along the same road at an average speed of . Calculate the average speed for the round trip. (And don't say i) To receive full credit, you must do this calculation without assuming a numerical value for the distance or the time. (9 points) 3. A metro bus starts from rest and travels between two stops that are apart. The driver accelerates at over the first , and then continues at constant velocity until before the second bus stop. A) What rate of uniform acceleration must the driver use from this point in order to come to a complete halt at the bus stop? B) What is the total time between the two bus stops? (14 points) 4. A child throws a ball straight upward with a speed of 24.1 . The ball is caught on the way down at a point above the point from which it was thrown. Determine the speed of the ball when it was caught and the total length of time the ball was in the air. (13 points) 5. A small cart has an initial velocity of 3.44 to the right and accelerates at a constant rate of along a straight line. Determine: A) the speed of the cart after 8.2 seconds have elapsed, B) the average speed of the cart during this 8.2 second interval, and c.) the distance traveled by the cart during this same time interval
