Homework Help: physics

Posted by waqas on Saturday, August 6, 2011 at 9:17am.

To test your friend's claims about his car, you accept his o er of a ride about campus. Not wanting to exceed the speed limit, he claims he can only give a taste of the accelerating ability of his car and not the full proof. You notice, however, that the pine tree scented (and shaped) air freshener that hangs from his rear view mirror makes an angle of 25.1degrees with the vertical while he is accelerating.
(a) What is the car's acceleration (m/s2 )?
(b) What is the tension (N) in the string of the 100-g air freshener (assume only one
string hanging from the mirror)?
