What is the equation for the central force on an object moving in a circular path?

A child of mass m rides on a Ferris wheel as shown in figure (a). The child moves in a vertical circle of radius 12.2 m at a constant speed of 2.75 m/s. a circular path at a constant speed. To yield net force vectors with the same magnitude, the normal force at the bottom must be ---Select-- v that at the top. Categorize Because the speed of the child is constant, we can categorize this problem as one involving a particle (the child) ---Select- v, complicated by the gravitational force acting at all times on the child. Тор , Analyze (Use the following as necessary: not m, and g.) We draw a diagram of forces acting on the child at the bottom of the ride as shown in figure (b). The only forces acting on him are the downward gravitational force F, = mg and the upward force n exerted by the seat. The net upward force on the child that provides his centripetal acceleration has a magnitude Fnet.bottom mg Using the particle in uniform circular motion model, apply Newton's second law to the…

A 2-stage rocket is fired from rest. Its acceleration data are shown in the graph below. Plot the v-t and s-t graphs describing the motion of the rocket-clearly showing the shape of the curve (or add a note) and values at inflection points. Show any calculations as well. Then find the velocity of the rocket and its elevation after 20 seconds of flight. a (m/s?) 25 18 (s) 15 20

A 30 kg object is moving in uniform circular motion with a radius of 10 m. It takes the object 2 s to make one complete revolution. Find the net force acting on the object.
