Chapter 2, Problem 1CQ

A person gets in an elevator on the ground floor and rides it to the top floor of a building. Sketch a velocity-versus-time graph for this motion.

Expert Solution & Answer

To determine

To draw: The velocity-versus-time graph.

Answer to Problem 1CQ

The velocity-versus-time graph is drawn.

Explanation of Solution

Given data:

A person gets in an elevator on the ground floor and rides it to the top floor of a building.

Explanation:

Normally when the elevator starts to function, initially the speed or velocity will be low and then gradually increases its speed. In the middle period of the elevator functioning, the speed becomes constant and at end period speed slows down and comes to rest.

The velocity-versus-time graph for the above scenario is shown in Figure 1.

COLLEGE PHYSICS:STRATEGIC APPR.AP ED., Chapter 2, Problem 1CQ

Initially graph starts from zero, gradually increases. During middle period velocity remains constant showing horizontal line in the graph. During end period there will be gradual decrease and end at zero in the graph.

Conclusion:

Hence, the velocity-versus-time graph is drawn.

4 Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = rad, the angular speed of the arm is ė = 1 rad/sec, and the angular acceleration is = 2 rad/sec². What is the net force acting on the 1 kg particle at this instant? Express your answer as a vector in cylindrical coordinates. Hint: You can express the radial coordinate as a function of the angle by observing a right triangle. (20 pts) Ꮎ 2 m Figure 3: Particle pushed by rod along vertical path.
