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

i was thinking more like reflects green light, just not sure

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
