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.

Consider the system shown in the figure below with m1-20 kg, m2-12.5 kg. R-0.2 m, and the mass of the puilley M-5 kg. Object m2 is resting on the floor, and object m1 is 4 m above the floor when it is released from rest. The pulley axis is frictionless. The cord is massless, does not stretch, and does not slip on the pulley. a. Calculate the time interval required for m1 to hit the floor. b. How would your answer change if the pulley were massless?
In 1956, Frank Lloyd Wright proposed the construction of a mile-high building in Chicago. Suppose the building had been constructed.

The Gravitron ride has people step in, lean against a wall and “stick” when it spins and the floor drops out after a certain velocity. A rider has a mass of 50kg. The coefficient of static friction of the body against a wall is 0.8. The diameter of the ride is 10m. What is the maximum period of the ride’s rotation that will keep the student pinned to the wall once the floor drops?

A person is pushing a fully loaded 24.55 kg wheelbarrow at constant velocity along a plank that makes an angle a = 43.0° with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its L. What is the magnitude of the total force F the person must apply so that the wheelbarrow is parallel to that plank? You may neglect the radius of the wheel in your analysis. The gravitational acceleration is g = 9.81 m/s². F = N
