To test your fhe brother's claims about his car, you accept his offer 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 the car by accelerating for just a second or two. this is not long enough to get a good reading on the speed and the elapsed time. you notice, however, that the pine tree scented (and shaped) air freshener that hangs from his rear view mirror makes an angle of 24.6 degrees with the vertical while he is accelerating. what is the car's acceleration?
