We know an object moving in a circle at constant speed feels a centripetal acceleration inward towards the center of the circle. Two students are arguing about this in the context of Newton's 2nd/1st law. One says that since the speed is constant Newton's 1st law says the net force is zero. The other says that since there is a net acceleration points to the center of the circle the net force must also point in to the center of the circle and be non-zero. Who is right

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
