Acar drives at a constant speed of 14 m/s around a circle with radius 55 m. what is the centripetal acceleration of the car? a. 2.3 m/s2 b. 3.6 m/s2 c. 3.9 m/s2 d. 0.25 m/s2

Option (B) is correct. a= 3.6 m/s²

Explanation:

The centripetal acceleration is given by

a= v²/r

v= velocity=14 m/s

r= radius=55 m

a= (14)²/(55)

a=3.6 m/s²

Answer : The correct option is, (B)

Explanation :

The formula used for centripetal acceleration is:

where,

= centripetal acceleration = ?

v = velocity of car = 14 m/s

r = radius = 55 m

Now put all the given values in the above formula, we get:

Therefore, the centripetal acceleration of the car is

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
