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

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

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the answer to this is proletariats.

hope this : )
