UIC PHYSICS 105 Spring 2013 Practice Exam 1
MULTIPLE CHOICE QUESTIONS (2 points each) Clearly circle the letter of the best answer MCQ 1: The figure to the right represents the position of a particle as it travels along the x-axis. At what value of t is the velocity of the particle equal to zero? (A) 1 s Answer: velocity = slope of x vs t line (B) 2 s slope = 0 at t = 3 s (C) 3 s (D) 4 s
MCQ 2: A runner runs around a track consisting of two parallel lines 96 m long connected at the ends by two semicircles with a radius of 49 m. She completes one lap in 100 seconds. What is her average velocity? (A) 2.5 m/s ∆ (B) 5.0 m/s Answer: 0 m/s ∆ ∆ (C) 10 m/s (D) 0 m/s MCQ 3: You drop a very bouncy rubber ball. It falls, and then it hits the floor and bounces right back up to you. Which of the following represents the v vs. t graph for this motion?
Answer: Initially, the ball is falling down, so its velocity must be negative (if UP is positive). Its velocity is also increasing in magnitude as it falls. Once it bounces, it changes direction and then has a positive velocity, which is also decreasing as the ball moves upward. MCQ 4: Two objects are dropped from a bridge, an interval of 1.0 s apart. During the time that both objects continue to fall, their separation Object 1: , . (A) increases. (B) decreases. Object 1: , . (C) stays constant. If t1 > t2 , , , , , , (D) increases at first, but then stays constant. then and the separation between two objects x1 – x2 increases
