A car starts from rest on a curve with a radius of 150 m and tangential acceleration of 1.5 m/s2
Through what angle will the car have traveled when the magnitude of its total acceleration is 3.0 m/s2 ?
Answered by Abby
A loudspeaker of mass 16.0 kg is suspended a distance of h = 2.00 m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 2.90 m

What is the tension T in each of the cables?
Use 9.80 m/s2 for the magnitude of the acceleration due to gravity.
