Ok I see. And just to clarify, if I divide a linear acceleration by the radius R then we get angular acceleration? Nvm! Figured it out. Thank yoooou! :)

Ohhh, you're right about the a/R not α/R. But can you explain to me why does a/R = ay?

Homework Statement This is not really a question on how to solve the problem, I'm just trying to get clarification on something. For angular acceleration, α, can someone explain to me what αz is? And why does αz = α / R = αy? I understand the rest of the problem, I just don't understand...

***Sorry I meant to say finding time when you have initial velocity and position*** 1. Homework Statement A test rocket is launched by accelerating it along a 200.0-m incline at 1.36 m/s2 starting from rest at point A (the figure (Figure 1) .) The incline rises at 35.0 ∘ above the horizontal...

Oh I get it! The equation I should be using is v2 = Vo2 + 2a(x-xo) Then just plugging in the values given would be: (17m/s)2 = 0 + 2a(117m) -algebra stuff- a = 1.24 m/s2 Then to find time I would use x(t) = xo + vot + 1/2at2 117m = 0 + 0 + 1/2(1.24m/s2)t2 -algebra stuff- t = 13.8 s Then for...

Homework Statement A car sits in an entrance ramp to a freeway, waiting for a break in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line...
