In Earth, there is a gravitional force. So that forces pushed you down faster.
Answer:
![x = 30cos\frac{\pi}{6}t](https://tex.z-dn.net/?f=x%20%3D%2030cos%5Cfrac%7B%5Cpi%7D%7B6%7Dt)
![y = 30sin\frac{\pi}{6}t + 45](https://tex.z-dn.net/?f=y%20%3D%2030sin%5Cfrac%7B%5Cpi%7D%7B6%7Dt%20%2B%2045)
Explanation:
1 full revolution is
let \theta be the angle of Ron's position.
At t = 0. ![\theta = 0](https://tex.z-dn.net/?f=%5Ctheta%20%3D%200)
one full revolution occurs in 12 sec, so his angle at t time is
![\theta =2\pi \frac{t}{12} = \frac{\pi}{6}t](https://tex.z-dn.net/?f=%5Ctheta%20%3D2%5Cpi%20%5Cfrac%7Bt%7D%7B12%7D%20%3D%20%5Cfrac%7B%5Cpi%7D%7B6%7Dt)
r is radius of circle and it is given as
![x = rcos\theta](https://tex.z-dn.net/?f=x%20%3D%20rcos%5Ctheta)
![y = rsin\theta](https://tex.z-dn.net/?f=y%20%3D%20rsin%5Ctheta)
for r = 30 sec
![x = 30cos\frac{\pi}{6}t](https://tex.z-dn.net/?f=x%20%3D%2030cos%5Cfrac%7B%5Cpi%7D%7B6%7Dt)
![y = 30sin\frac{\pi}{6}t](https://tex.z-dn.net/?f=y%20%3D%2030sin%5Cfrac%7B%5Cpi%7D%7B6%7Dt)
however, that is centered at (0,0) and the positioned at time t = 0 is (30,0). it is need to shift so that the start position is (30,45). it can be done by adding to y
![x = 30cos\frac{\pi}{6}t](https://tex.z-dn.net/?f=x%20%3D%2030cos%5Cfrac%7B%5Cpi%7D%7B6%7Dt)
![y = 30sin\frac{\pi}{6}t + 45](https://tex.z-dn.net/?f=y%20%3D%2030sin%5Cfrac%7B%5Cpi%7D%7B6%7Dt%20%2B%2045)
