A particle moves along a circular path of radius 10 ft. If its position is 8 = 0.74 - 1 rad, where t, is in seconds, determine the magnitude of the particle's acceleration when 8 = 0.53 radians. Note that the magnitude is a scalar, if you were asked for acceleration you would need to give a vector Give answer to at least 3 decimal places jäl =
Please help! :) Discussion #3 1. Consider the motion of an object that can be treated as a point particle and is traveling counter-clockwise in a circle of radius R. This motion can (and will for the purposes of these discussion activities) be described and analyzed using a Cartesian (x-y) coordinate system with a spatial origin at the center of the particle's circular trajectory (the physical path its motion traces out in space). (a) Draw a diagram of the position...
The position of a particle as a function of time is shown in the figure. What is the particle's average velocity between time t = 0.6 s and time t = 7.2 s? What is the average speed of the particle between time t = 0.6 s and time t = 7.2 s? What is the average acceleration of the particle in the time interval between t = 0.6 s and t = 7.2 s?
Learning Goal: To find the velocity and acceleration vectors for uniform circular motion and to recognize that this acceleration is the centripetal acceleration. Suppose that a particle's position is given by the following expression: r⃗ (t)=R[cos(ωt)i^+sin(ωt)j^] =Rcos(ωt)i^+Rsin(ωt)j^. Part C Find the particle's velocity as a function of time. Express your answer using unit vectors (e.g., A i^+ B j^, where A and B are functions of ω, R, t, and π). Part D Find the speed of the particle at...
