Samantha drives her car of mass 800kg clockwise around a circular track of radius 60m. she completes 12 laps around the track in 4 minutes. find samantha's centripetal acceleration in m/s2

5.92

Explanation:

       The motion of the car can be described as uniform motion in a circle. Hence, speed of the car is assumed constant.

       She completes 12 laps in 4 minutes. So each lap takes 20 seconds.

       Radius of lap = .

Mass of car =

       Centripetal acceleration =

∴ Centripetal Acceleration = 5.92

No it doesnt because it can be any number.

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.
