Acyclist rides at a constant speed of 4.5 m/s around a curve. if the centripetal acceleration is 29 m/s2, what is the radius of the curve? a) 0.16 m b) 0.70 m c) 6.4 m d) 34 m

B) 0.70 m

Explanation:

The centripetal acceleration is given by:

where

v is the speed (tangential speed)

r is the radius of the curve

In this case, we know the speed, v=4.5 m/s, and the centripetal acceleration, a=29 m/s^2, so we  can re-arrange the equation above to find the radius of the curve:

answer: i pick a

explanation:

come closer and become far apart and become steam/gas
