Question

Understand how to find the equation of motion of a particle undergoing uniform circular motion. Consider a particle--the small red block in the figure--that is constrained to move in a circle of radius . We can specify its position solely by , the angle that the vector from the origin to the block makes with our chosen reference axis at time . Following the standard conventions we measure in the counterclockwise direction from the positive x axis. (Figure 1)

Following the standard conventions we measure in the counterclockwise direction from the positive x axis. (Figure 1) Part B For uniform circular motion, find /theta/left(t/right) at an arbitrary time t . Give your answer in terms of /omega and t . The answer is: omega^*t The part I really need help with is this one: Part C What does /vecr/left(t/right) become now? Express your answer in terms of R , /omega , t , and unit vectors /hati and /hatj .

Explanation / Answer

c. The x component of r(t)=Rcos i = Rcos(wt) i

The y component of r(t)=Rcos j= Rsin(wt) j

r(t)=R{cos(wt) i + sin(wt) j}
