An object initially at rest experiences art acceleration of 2.00 m/s 2 on a level surface. Under these conditions, it travels 6.00 m. Let's designate tire first 3.00 m as phase 1 with a subscript of 1 for those quantities, and the second 3.00 m as phase 2 with a subscript of 2. (a) Tire times for traveling each phase should be related by which condition: (1) t 1 t 2 , (2) t 1 = t 2 , or (3) t 1 t 2. (b) Now calculate the two travel times and compare them quantitatively.
