Basic Calculus/Quiz #4/February 20, 2012 SOLUTIONS We can write s ( t ) = 48 + 96 t - 16 t 2 = - 16( t 2 - 6 t - 3). 1. (a) v ( t ) = s 0 ( t ) = 96 - 32 t = 0 when t = 3. (b) s (3) = - 16(9 - 18 - 3) = 16 × 12 = 192 ft. (c) We solve s ( t ) = 0. This gives t = 6 ± 36 + 12 2 = 3 ± 2 3. We discard the negative value and get t = 3 + 2 3

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
