[MC Squidge]

A mass of 1kg is fastened by a string of length 1m to a point 0.5m above a smooth horizontal table and is describing a circle on the table with uniform angular acceleration of 1 revolution in 2 seconds. Find the force exerted on the table and the tension in the string.

i have a solution but they lost me at the red astrix

earlier (before the *) they derived to equations:

T=ml(w^2)

N+Tcosx=mg

solve simultaneously and you got it
