Arace car has a centripetal acceleration of 18.75 m/s2 as it goes around a curve. if the curve is a circle with radius 12 m, what is the speed of the car? a. 15 m/s b. 9.8 m/s c. 1.6 m/s d. 17.2 m/s

Option (A) is correct.

Explanation:

The centripetal acceleration is given by

a= v²/r

V= velocity

r= radius= 12 m

a= centripetal acceleration= 18.75 m/s²

18.75= v²/12

v²=18.75 x 12

v²=225

v= 15 m/s

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
