A wheel with radius 2 cm is being pushed up a ramp at a rate of 7 cm per second. The ramp is 790 cm long,
and 250 cm tall at the end. A point P is marked on the circle as shown (picture is not to scale).

250 cm
Write parametric equations for the position of the point P as a function of t, time in seconds after the ball
starts rolling up the ramp. Both x and y are measured in centimeters.

You will have a radical expression for part of the horizontal component. It's best to use the exact radical
expression even though the answer that WAMAP shows will have a decimal approximation.
