When you have finished, submit this assignment to your teacher by the due date for full credit. Total score: ____ of 31 points (Score for Question 1: ___ of 8 points) 1. A baseball is thrown straight upward. Describe the direction and magnitude of the velocity, force of gravity, and the varying air resistance force as the ball rises. Explain whether the net force increases, decreases, or is unaffected by the air resistance force. Repeat for the part of the motion when the ball is at maximum height and the part of the motion when the ball is moving downward Answer: Type your answer here. (Score for Question 2: ___ of 8 points) 2. A ball is thrown horizontally from a platform so that the initial height of the ball is 6.0 m above the level ground below. The ball lands 24 m from its original horizontal location. Find how fast the ball was thrown. Show all work. Answer: Type your answer here. (Score for Question 3: ___ of 7 points) 3. A car is driven at constant velocity along a level highway. Indicate the value of the net force and list all the main forces acting on the car to produce the net force. Clearly explain what produces or exerts each of the contact forces acting on the car and explain which forces are balanced. Answer: Type your answer here. (Score for Question 4: ___ of 8 points) 4. Summarize two observations that are contrary to the predictions based on Newton’s laws but that confirm Einstein’s explanation of gravity.
