(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

There are two balls with masses m_a and m_b connected by a string. m_b is moving at a velocity v upwards (perpendicular to the string) and it asks for the Tension (T) in the string.

2. Relevant equations

a=(v^2)/R

delta Energy of system = 0

T = m((u^2)/r)

u is linear speed of rotational motion

r = radius of motion

3. The attempt at a solution

The initial kinetic energy of m_b = .5(m_b)v^2

and that's as far as I got.

Is mass B moving?

how do I start this problem?
