A physicist’s car has a small lead weight suspended from a string attached to the interior ceiling. Starting from rest, after a fraction of a second the car accelerates at a steady rate for about 10 s. During that time, the string (with the weight on the end of it) makes a back-ward (opposite the acceleration) angle of from the vertical. Determine the car’s (and the weight’s) acceleration during the 10-s interval.
