circular racing track in one minute. Find the
radius of the track if the car has a uniform
centripetal acceleration of n' m/s?.
A car driving around a circular track has a centripetal acceleration of 97 m/s2 until it hits a slick spot and slides straight off the track.
If the radius of the track is 61 m, what is the car's speed v when it leaves the track?

On December 10, 1954, Stapp rode a rocket sled, accelerating form rest to a top speed of 282 m/s (1015 km/h) in 5.00 s and was brought jarringly back to rest an only 1.40 s.
