A 45.0 cm diameter wheel accelerates uniformly from 205 rpm to 385 rpm in 7.5 s. How far will a point on the edge of the wheel have traveled in this time?
w^2=v^2 + 2ah
The Attempt at a Solution
So, I converted 205 rpm and 385 rpm to rad/s. Then I found angular acceleration by using the formula: a=(w-v)/t. Then I plugged everything into the equation: w^2=v^2 + 2ah and solved for h(theta). Then I converted h(theta), which was in radians, to meters by multiplying it by the radius because h(theta)=s/r. Apparently that's the wrong way though, so if anyone could help me out, I'd love him/her forever. Thank you!
