If the angular speed is 3.5 rad/s in the counterclockwise direction, the radius of the circular groove is 0 73 m and the angular position of the ban at r is e-o, determine the x component or the ball's position at the times 1.0 s, 40 s and S5·Assurn" e Ses along the +x axis.) x( 1.0 s) = x(t 5.5 s) #1 Supporting Materials Physical Constants Additional MaExplanation / Answer
given
w = 3.5 rad/s
r = 0.73 m
at t = 1s,
x(t=1.0s) = r*cos(theta)
= r*cos(w*t)
= 0.73*cos(3.5*1)
= -0.684 m
at t = 4s,
x(t=4.0s) = r*cos(theta)
= r*cos(w*t)
= 0.73*cos(3.5*4)
= 0.10 m
at t = 5.5s,
x(t=5.5s) = r*cos(theta)
= r*cos(w*t)
= 0.73*cos(3.5*5.5)
= 0.67 m
