A70 kg man rides a ferris wheel with a radius of 10.3 m at a velocity of 5.00 m/s . what is the centripetal force that he experiences, expressed with the correct number of significant figures? the formula for determining centripetal force, in newtons, is f=mv2r .

169 n

169.9 n

170 n

200 n

i don't know if it's 169.9 or 170 and explain

200 N

Explanation:

F = mv²/r

F = (70 kg) (5.00 m/s)² / (10.3 m)

F ≈ 200 N

The man's mass is precise to only 1 significant figure, so you must round the final answer to 1 significant figure.

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
