4.5minutes*60 secs

I'll take note. Thank you

≈1.5386 rad/s

θƒ = 23.672 rads (??)

α = 5.00 * 10^-2 rad/s^2 θƒ = 162m Oooh, I get it now I got the wrong θi. It should be 0

*rad/s (some Freudian slip there hehe if the units is the only thing wrong)

3.4496 m/s

Oh yes that's what I meant. I tend to forget the proper symbol

ωf2 = ωi2 + 2a (θf - θi)

So I did this: ωf = √2(5*10^-2 rad/s^2)(162m-43m). I got 3.446 m/s

vf ^2 = vi^2 + 2aΔx

Homework Statement African baobab trees can have circumferences of up to 43.0 m. Imagine riding a bicycle around a tree this size. If, starting from rest, you travel a distance of 162 m around the tree with a constant angular acceleration of 5.00 × 10–2 rad/s2, what will your final angular...
