AP PHYSICS C ELECTRICITY AND MAGNETISM Unit 1 Progress Check MCQ and Scoring Guide 2023/2024. A ball is thrown into the air with an initial velocity of 10 m/s at an angle of 45 degrees above the horizontal, as represented above. Which of the following representations of the velocity and acceleration of the ball is true? - C. At Highest Point: velocity points to right and acceleration points downwards A ball is thrown into the air with an initial velocity of 10 m/s at an angle of 45 degrees above the horizontal, as represented above. If air resistance is negligible, the time needed for the ball to return to the ground is most nearly - B. 1.42s The figure shows a block on a horizontal surface with the velocity v and acceleration a vectors shown. Which of the following best describes the motion of the box at the moment shown? - C: The block is moving to the right and slowing down. Figure 1 shows a person dropping a coffee filter to the floor. As the filter drops, air resistance will cause the acceleration to decrease with time. Figure 2 shows the velocity v and acceleration a vectors a short time after the filter is dropped. Which of the following could show the velocity and acceleration vectors a short time after Figure 2? - D: Velocity is largest magnitude and pointing downwards, acceleration is smallest magnitude pointing downwards
