As a moon orbits a planet, its angular position is given by Kepler's equation
where is some constant.
(a) If it takes 50 days for the moon to complete an orbit, what it the value of ?
(b) Find the rate of change when .
|Remember that 1 revolution is radians.|
|At , the moon has made 1 full revolution so radians and . You can use this to find .|
|To find , consider differentiating both sides of the equation with respect to time, and use the chain rule on the right hand side. Then isolate (solve for) . Only plug in the value at the very end.|
