A person drives a car around a circular cloverleaf with a radius of 58 m at a uniform speed of 10 m/s. ) Compare this answer with the acceleration due to gravity as a percentage

• physical science -

Centripetal acceleration
a=v²/R=10²/58 = 1.72 m/s²

9.8 ....100%
1.72.....x%
x=1.72•100/9.8 =17.6%
