Answer 1

Hey LDW. Me again with my dumb homeworks..

Answer 2

Gravitron is fun.

Answer 3

Lol never been on one.

Answer 4

This time im completely lost on what to do. Not good with friction.

Answer 5

and motion.

Answer 6

In part(a) we have to calculate centripetal acceleration given the velocity and radius.
It's a kinematics question so we can ignore the dynamics (Simply use the formula ;)

But to find its relation with g (later half of part a) and to solve other parts ; we need to draw a free body diagram for the block.

Start with drawing the FBD ; we'll assist you along the way.. :)

Answer 7

Mmkay lemme try to draw that.

Answer 8

Only forces affected by it is... normal and gravity, right?

Answer 9

There's also the force that holds you against the wall, centripital force.

Answer 10

Teacher didn't teach us that part though.. not sure which direction Cf goes..

Answer 11

When the gravitron is spinning, you could be 5 feet off the ground and you wouldn't fall. So what direction is the force?

Answer 12

(I'm actually speaking from experience; I've been in a gravitron.)

Answer 13

Gotcha.
