Aperson drives a car around a circular cloverleaf with a radius of 63 m at a uniform speed of 10 m/s. (a) what is the acceleration of the car? (b) compare this answer with the acceleration due to gravity as a percentage?

acceleration is 1.59 m/s²

required % is 16.22 %

Explanation:

given data

radius = 63 m

speed = 10 m/s

to find out

acceleration of the car and acceleration due to gravity

solution

we know car is moving in circular path

so acceleration will be, a =   .........1

put here value

a =  

a = 1.59 m/s²

so acceleration is 1.59 m/s²

so acceleration due to gravity as a percentage is 9.8 m/s²

required % =

required %  = 16.22 %

the answer is b, have negligible mass
