Science Discussion Group April 15 2015, 9:03 amThe circular motion of a particle in the x-y is given by the equations:
r(t)= 7.23m
Theta(t)= (6.33rad/s)t
Where r is the distance from the origin and Theta is the polar angle measure counterclockwise from the positive x-axis. Calculate the x-coordinate of the particle at time t=2.50s April 15 2015, 9:03 am
