Question

A 0.2kg mass attached to the end of a spring is whirled in a vertical circle by a student. At some position, the mass experience a downward force of –62jN and a horizontal force 38i N. Determine its acceleration in the position.

Answer 1

a=363.593m/s*2 we have rectangular component of force so we first find force resultant by square both component then square root and finally divide with 0.2 kg mass
