A car of mass 1500 kg is negotiating a flat circular curve of radius 50 m with a speed of 20 m/s. a. The source of centripetal force on the car is (1) the weight of the car, (2) the normal force on
the car, or (3) the static friction force.
b. What is the magnitude of the centripetal acceleration of the car?
c. What is the magnitude of the centripetal force on the car?
d. What is the minimum coefficient of static friction between the car and the curve?
I’m

the answer is c

Explanation: niform Circular motion  fancy math dc = y² at. The net the. Center force is towards. EF=ma  A car is negotiating a flat curve of radius 50.0 m with a speed of 20.0 m/s. is 12000 N. What is the mass of the car? 12000 = m. 204. - 50. M=1500 An electron (m=9.11x10-31 kg) moves in a circle whose radius is 2.00 x 102 m.

it takes about 30 days for it to break down

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
