Homework Statement
An electron's position is given by r(t)=r(0)+c1*t, θ(t)=θ(0)+c2*t, where r(0), c1, θ(0), and c2 are known constants. What is the kinetic energy of the electron? (mass=m)
Homework Equations
KE=(1/2)Iω2=(1/2)mr2ω2
The Attempt at a Solution
plugging in m for mass, r(0)+c1*t for radius, and c2 for ω
(1/2)(m)(r(0)+c1*t)2(c2)2
This isn't the correct answer, so I'm fairly certain I've messed up on my "r" value somehow.
It's supposed to equal (1/2)(m)(c12+r2c22)
Where am I going wrong?
