Checking up 1. 2. 3. 4.

PTG 1. I would check that every point is under 4g's, that the track is strong enough to support forces and that there is enough speed to get over loop (1<a<4) 2. 3. 4.

5. 6. a. b. 7. 8. a. No, a change in mass doesn't change the centripetal acceleration b.The speed of the roller coaster doesn't depend on the mass c.Yes, more Normal force is needed
