An object is revolving in a vertical circle of radius 9.8 m, with a velocity which is just enough to make it ?

complete the loop. Find the


change in velocity of the object when it reaches from


position A to position C (AC is horizontal line


parallel to earth's surface)


An object is revolving in a vertical circle of radius 9.8 m, with a velocity which is just enough to make it ?
Fgravity down = M*A Where A = 9.8 m/s^2





Centripital Force = M (V^2/r)





At the top these balance





M*A = M*(V^2/r)





M cancels





9.8 - V^2/9.8





V^2 = 9.8 * 9.8 =





V=9.8 m/s





You finish
