Question
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 .
Hints
Hint 1 |
---|
Remember that 1 revolution is radians. |
Hint 2 |
---|
At , the moon has made 1 full revolution so radians and . You can use this to find . |
Hint 3 |
---|
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. |
