work power energy question 2

Fcosθ = mw²r

Fsinθ = mrα

now w = d(π-2θ)dt = - 2dθdt

α = - 2 d²Î¸dt²

henced²Î¸dt²(dθdt)²= - α2w²4

= -2αw² = -2tanθ

great thanks a lot sir...............

abe main kaha ka sir [3] [3]

u r 18, i m 17 [3] [3]

baad mai tunhari profile padhi ho jati hai galti well thanks nice work yaar those ques were troubling me.................................
