A car starts from rest on a curve with a radius of 140 and accelerates at 1.20 . How many revolutions will the car have gone through when the magnitude of its total acceleration is 3.50 ?
If someone could just get me started. Im new to this stuff. I don't understand how if somethign is moving at an acceleration of 1.2 m/s^2 then it can comehow go at 3.5 later. Im guessing the MAGNITUDE has something to do. Any help would be great!
I'm not a physics man but I think you should repost and make sure the units show if you want an answer. 140 what and 3.50 what?
