A mechanic jacks up a car to an angle of 8 degress to change the front tires. The car is 3.05 m long and has a mass of 1130 kg. Its center of mass is located 1.12 m from the front end. The rear wheels are .4 m from the back end. Calculate the torque exerted by the car around the back weels...

Why is "L" the angular momentum I was wondering why is L used as the symbol for angular momentum? :bugeye:

T If i did it correctly i got a T of 1.96. Is that the right answer?

What is I? I'm not sure what I is... is it equal to 1/2(.5).075^2?

Thanks Thanks...i'm going to go solve it now. And sorry for double topics...i didn't realize i was posting a high school problem in the college section so i decided to post it again. Sorry

Question: A light string 4 m long is wrapped around a cylindrical spool with a radius of 0.075 m and a mass of .5 kg. A 5 kg mass is then attached to the free end of the string causing the string to unwind from the spool. a) What is the angular accelerataion of the spool? b) how fast...
