Question: Part A) A mass of 0.134 ± 0.005 kg, set at the radius 9.5 ± 0.1 cm, undergoes uniform circular motion with the angular velocity 8.6 ± 0.2 rad/s. What is the centripetal force acting on the mass? Part B) A mass of 0.133 ± 0.005 kg, set at the radius 7.9 ± 0.3 cm, undergoes uniform circular motion with the angular velocity 14 ± 0.4 rad/s. What is the uncertainty in the centripetal force acting on the mass?
Conceptual Question: Use Newton's First Law to explain why there must be a force constantly acting on any object in circular motion, even if it is staying at constant speed. Use Newton's Second Law to write an equation for the centripetal force in terms of the speed and radius of the object's motion as well as to determine the direction in which the force points Newton's Third Law is true in all stuations, including circular motion. Explain why the equal...
The direction of the centripetal force is always in the same direction a. as the centripetal acceleration vector b. as the velocity vector c. that an object would have if the centripetal acceleration suddenly stopped d. as the direction of motion of the object In this question, "constant in direction" refers to a fixed direction such as east or west. For uniform circular motion, the acceleration vector is a. changing in magnitude but constant in direction b. constant in magnitude...
One end of a spring with a force constant of k 10.0 N/m is attached to the end of a long horizontal frictionless track and the other end is attached to a mass m = 2.20 kg which glides along the track. After you establish the equilibrium position of the mass-spring system, you move the mass in the negative direction (to the left), compressing the spring 1.73 m. You then release the mass from rest and start your stopwatch, that...
Due Date: 2/28/2020 (F) Spring 2020 Dynamics HW5-1 Student Name: Chapter 13 Kinetics of a Particle: Force and Acceleration Chapter 13.1 Newton's 2nd Law of Motion 1. Kinetics is a branch of dynamics that deals with the relationship between and that cause this change. 2. Newton's 2nd law states that when an ) acts on a particle, the particle will accelerate or decelerate in the direction of the force with a magnitude that is proportional to the force. 3. The...
(1 point) A body of mass 10 kg moves in the xy-plane in a counterclockwise circular path of radius 3 meters centered at the origin, making one revolution every 11 seconds. At the time t 0, the body is at the rightmost point of the circle. A. Compute the centripetal force acting on the body at time t. B. Compute the magnitude of that force. HINT. Start with finding the angular velocity o [rad/s] of the body (the rate of...
A hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutions) and releases it at a speed of 27.7 m/s A.) Assuming a uniform rate of increase in angular velocity and a horizontal circular path of radius 1.30 m , calculate the angular acceleration. B.) Calculate the (linear) tangential acceleration. C.)

Centripetal Force and Acceleration For a body in motion to ch force on a body is in the sa acceleration in that the speed i direction opposite to that of the velocit undergoing negative acceleration. In thes speed, not direction. In this lab we lo wdy in motion to change either its speed or direction, a force is required....
Objectives for Lab 3 (Free Body Diagrams, Circular Motion). Prove that forces are vectors and understand the difference between externally applied forces and internal reaction forces. 11 Explore uniform circular motion.
