Question

Astronauts often have to train in high-g (high gravity) environments before they embark on space missions. A space-training module consists of a capsule that rotates insides a horizontal circular track of radius 115 m. The rotational speed increases at a constant rate from rest such that the capsule finishes its first cycle in 8.00 s

(a) How long does it take from the start of the motion for the radial acceleration to be equal to five times the acceleration due to gravity

(b) How long does it take for the radial acceleration to be equal in magnitude to the tangential acceleration?
