Homework Statement Convert the following: From butane to 2,3-dimethylpent-2-ene Homework Equations organic synthesis The Attempt at a Solution Working forwards I get: Cl2 and light/separate yielding 1-chorobutane Working backwards I get: 2,3-dimethylpent-2-ene converted by I-...

Ok how is 1.60 m/s^2 for tangential and 8.61 m/s^2 for total acceleration?

Homework Statement roller coaster traverses a vertical circular track. a)what speed must car have to make it over the top w/o leaving the track? assume it is not attached to track. b)what will speed be at bottom? c)what will normal force on passenger be at the bottom of loop if radius is...

Homework Statement wheel rotates w constant acceleration 3.65rad/s2 angular speed is 3.00 rad/s at t=0 a)what angle does wheel rotate between t=0 and t=3.67s? b)what is angular speed of wheel at 4.1s? Homework Equations wt+1/2alphat (3.00rad/s)(3.67t)+1/2(3.65rad/s2)(3.67)2=17.70rad...

My teacher gave us this problem, but there is no other info given besides what I hvae. I have already emailed him and still have not got a response.:frown:

Thanks. Now if I could only figure out how you would get the tangential and total acceleration. There is no other information provided in the problem.:confused:

So here is what I came up with for magnitude and angular speed: 7.006m/s2 0.103rad/s

Yes, 660m is the radius of the track. No time is given all it states is that accelerates from 40 m/s to 84 m/s and to find all that info once the car reaches 68m/s Thanks

Homework Statement car speed from 40m/s to 84m/s traveling counterclockwise around a track 6.6x10^2m when it reaches 68m/s find: magnitude of centripedal acceleration angular speed tangential acceleration magnitude of total acceleration Homework Equations ac=v^2/r w=v/r at=...
