An object is moving in the plane according to these parametric equations:
x(t) = πt + cos(4πt + π/2)
y(t) = sin(4πt + π/2)
a portion of the "cycloidal" path (on the time interval [0,1]) is shown in this figure:
at time t=0, the object is located at (0,1). give exact answers to all questions below; use pi to denote the number π.
(a) the horizontal velocity is .
(b) the vertical velocity is .
(c) the slope of the tangent line to the path at time t is
(d) the equation of the tangent line to the path at time t=1/6 is
y = (x - ) +
(e) the first time the tangent line is vertical will be t=
(f) the second time the tangent line is vertical will be t=
(g) what is the maximum horizontal velocity?
(h) what is the minimum horizontal velocity?
(i) the speed of the object at time t is s(t)=
(j)compute s'(t)=
(k) the maximum speed is
(l) the minimum speed is
