103. (a) With Δ x = 8.0 m, t = Δ t 1 , a = a x , and v ox = 0, Eq. 2-15 gives 8.0 m = 1 2 a x ( Δ t 1 ) 2 , and the corresponding expression for motion along the y axis leads to Δ y = 12 m = 1 2 a y ( Δ t 1 ) 2 . Dividing the second expression by the first leads to /3 / 2 yx aa = = 1.5. (b) Letting t = 2 Δ t
