Question

11. A 10kg object is instially moving vertikaly upward at 3 m/s It tho force of 10 N for 4 seconds What is the speed of the object after B) 7 ms net hortronta IB . A collar of mass a Is aftached to a spring friction along a circular rod of radias r spring has an unestretched length r and a spring f The collar is released from resd at polnt A Given that the distane d_ ns, what ollar's kinctic energy who. и reaches pint nd slides without orce constant in a vertical plane. The 10. A small block is released from rest at point A on an frictionless ramp as in the diagram at right. It then goes Into a frictionless ciecular loop-the-A of radias r What is the minlmum height babove the bottiom of the track such that the block moves around the inside of the loop without leaving the track at point B?
