Homework Statement
If an object moves in a circular path with a speed that increases at a constant rate, which of the following can be concluded?
(A) The radial component of the force acting on the object is zero.
(B) The net force acting on the object is zero.
(C) The net force acting on the object is directed toward the center of the circle.
(D) The net force acting on the object has a radial component and a tangential component that are equal at all times
(E) The tangential component of the force acting on the object is constant.
Homework Equations
Centripetal force = mass times centripetal acceleration.
The Attempt at a Solution
I[/B] learned that speed is constant in circular motion, so does its centripetal force and acceleration. Velocity is tanget to the force and acceleration and that’s why it accelerates while maintaining its speed. But for this situation why and how the speed is increasing. I have no idea.
