No i think you're confusing horizontal and vertical... vertical suggest there is a downward force due to gravity (aka 9.81...). However, here the path is horizontal, like a merry-go-round, so there gravity does not effect the tension on a frictionless surface. since the tension must be 16 or...

Oh I see. I'm unsure now how this would work since there are 2 variables that I need to find.

if its moving in a circular horizontal path the tension isn't mg its equal to the centripetal force (mv2/r) so I am guessing you set the centripetal force to equal 16 to solve for v. After that you can find the KE

Homework Statement A 5 g box moving to the right at 20 cm/s makes an elastic head on collision with a 10 g box initially at rest. Mass 1 = .005 kg initial Velocity 1 = .2 m/s Mass 2 = .01 kg initial Velocity 2 = 0 m/s a.) what velocity does each box have after the collision? b.) what...
