Position-Time Graphs & Velocity Practice Problems
An arrogant person arrives at the entrance of Company X. He is overconfident that he will be able to identify the interview location at the company by himself. After riding within the company for 16 min, he cannot locate the interview point and rides back to Company's entrance to get assistance from the personnel at the company entrance. The person's distance from the company's entrance is a function of time as shown below. What points represent velocity with decreasing magnitude?
A physicist who is an enthusiast in analyzing motions spots a dog making a chase in a straight line. The physicist uses a coordinate system where the motion is parallel to the x-axis and to the right is the +x direction. The physicist makes measurements of the dog's motion and constructs a graph of velocity as a function of time. Make a sketch of a graph to represent the acceleration and position as functions of time (Assume the dog starts at the origin).
A physics student with a strong interest in analyzing motions spots a dog making a chase in a straight line. The student uses a coordinates system where the motion is parallel to the x-axis and to the right is the +x direction. The student makes measurements of the dog's motion and constructs a graph of velocity as a function of time. Determine the dog's velocity at 2.5 s and 6.0 s.
A man leaves his house and walks toward the local marketplace. He meets an old friend after 7 min and aborts the journey to the market and both walk back to his house. The man's distance from his house is a function of time as shown below. What points represent constant and negative velocity?
An office messenger leaves the waiting area to deliver a parcel to a waiting client. The office messenger reaches the client's place after 12 min and returns to the waiting area. The messenger's distance from the waiting area as a function of time is shown below. What points represent constant and positive velocity?
A worker is driving home from the workplace. After 13.5 min, the worker realizes he forgot some confidential documents on the office table and returns to the workplace. The worker's distance from the workplace is a function of time as shown below. What points represent zero velocity?
