Arace car goes around a level, circular track with a diameter of 1.00 km at a constant speed of 89 km/h. what is the car's centripetal acceleration in m/s^2?

The car's centripetal acceleration is 1.22 m/s².

Explanation:

Given that,

Diameter of circular track

Radius r = 500 m

Constant speed

The centripetal acceleration is defined as,

Where, v = tangential velocity

r = radius

Put the value into the formula

Hence, The car's centripetal acceleration is 1.22 m/s².

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
