Question

A toy car of mass 200 g is moving on a circular path of radius 20 cm at a constant speed

v. It takes 8 s to complete one circle. What is the centripetal force,

acting on the car?

The answer is .024 N, I am only interested in the explanation of the problem. (if its just formulas its fine, just name each variable)

Answer 1

Answer #1

Angular speed is given by

m = 200 g = 0.2 kg

r = 20 cm = 0.2 m

Centripetal force is given by

= 0.2 × (π/4)² × 0.2 = 0.0247 N

body of mass 7 kg moves in a (counterclockwise) circular path of radius 4 meters, making one revolution every 13 seconds

body of mass 7 kg moves in a (counterclockwise) circular path of radius 4 meters, making one revolution every 13 seconds. You may assume the circle is in the xy-plane, and so you may ignore the third component. how do you find the centripetal force acting on the body how do you find the magnitude of the force??
