Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

8. A 1000 kg car travels from point A to
point B, rounding the turn of radius 70
meters with a constant speed of 60 km/hr.
a. What is the acceleration for the car?
b. How long does it take the car to get from point A to point B if the turn spans 90"?
c. What is the force of friction between the car and the road that is necessary for the car to
complete the turn?

9. At the right is an overhead view of two
masses, m1 = 3 kg and m2 = 2 kg, that are
connected to a central post by cords. Both
rotate about the post with the same period of
3.0 seconds. The horizontal surface on which
ml
they rest is frictionless with r1 = 10 cm and r2
= 20 cm. Determine the tension in each cord.
