Q.21 The normal force equals the magn... [FREE SOLUTION]

WebAnswer (1 of 2): At top of loop the loop: N+mg=mv^2/R N is zero only when moving at the minimum speed so that the object is not exerting a force on the loop. mg=mv^2/R so min. v=sqrt(gR) If going faster than that, N must exert a downward force so that the centripetal force is N+mg. BTW, mv^2/... WebImagine the vehicle falling just a fraction of a millimeter at the peak of the loop. The normal force is zero. That's just slightly too slow for the vehicle to properly complete the loop. …
