A 70 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 please help and explain

Answer:

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.
