As you drive down the road at 20 m/s you press on the gas pedal and speed up with a uniform acceleration of 1.16 m/s2 for 0.70 s. If the tires on your car have a radius of 33 cm, what is their angular displacement during this period of acceleration?

Angular acceleration related to linear acceleration as
A=a/R
and angular velocity relates to angular acceleration as
w=At
w=(a/R)t +w0 ; where w0=V0/R
w=(1.16/.33) 0.70 + 20/0.33
w=63.1 rad/s
Angular displacement= wt=63.1 x 0.70=44.1 radians
Note: The solution of Mistress Bekki is correct! the equation you must use is the one that she supplied. Our answers will appear to be close since the value of acceleration is small and applied for a short time. (The '1/2' term is missing in my equation)

Avoid the temptation to convert all the a's to alpha's and v's to omega's and x's to theta's right away. Sometimes that just increases your work. Do the linear problem first and fix it at the end. The distance covered is given by:
distance = v0 * t + 1/2 at^2
The angular displacement is given by:
theta = distance / r = (v0*t + 1/2 at^2) / r
They give you the initial speed (v0), the acceleration (a), the time (t) and the radius (r). Plugnchug. Don't forget to convert the cm to m to make the units work out right.

i does not do this that may not sturdy on your transmission your in fact doing a impartial drop witch even already at a roll your inflicting injury to the indoors areas. in case you opt for for extra skill or extra ideal acceleration then you definately ought to locate away to enhance your transmission or restoration your transmission. you will desire to purchase whats referred to as a shift kit they lead them to for many automobiles accessible you need to have a transmission shop deploy it and pass with a extra ideal torque converter. A shift kit will employer up the moving of the stress gears and administration while they shift to get the main out of the transmission and utilising adventure a smaller and distinctive stall converter will help you launch the vehicle from a lifeless end and look after torque.

Perhaps, but I'm not 100% on it
