A boy is swinging a toy on a piece of string in a vertical circle. The toy has a mass of 150g & the radius of the circle is 0.8m. A. he swings the toy with a linear velocity of 2m/s will the toy move in a circle? Explain your answer.

It will only move in a VERTICAL circle is there is tension in the string at all times, especially at the top of the circle, where the centripetal force M V^2/R must exceed the weight, M g.

Require that V^2/R > g for this to happen

g = 9.8 m/s^2 V^2/R = 5 m/s^2

It doesn't look good.

The toy will not move around a circle because the mv squared/r is less than mg force,with this speed
