We have to find the clearing

I am going to upload my work too. The answer is 290 Im getting around 99

θ=ωt θf=ωt+θi These were 2 equation that you mentioned in the last problem. What are they individually used for?

and I got no clue how I messed up on this problem xd

$$\color{#0cbb34}{\text{Originally Posted by}}$$ @darkknight θ=ωt θf=ωt+θi These were 2 equation that you mentioned in the last problem. What are they individually used for? $$\color{#0cbb34}{\text{End of Quote}}$$ Those are a few of the angular kinematics equations. In linear kinematics, you may know that: $$x=vt$$ where v=velocity, s=displacement, and t=time. Similarly in angular kinematics $$θ=ωt$$ where theta = angular displacement, t=time, and omega = angular velocity And the other formula you mentioned is kind of implied. If you have your initial position, and then have your angular displacement, you can find your final position.

Oh ok, so im sure the answer key messed up on this one so ill close the post
