So we are given [itex] a_{x} = 32 \frac{ft}{sec^{2}} [/itex], and [itex] v_{x}_{0} = 0 [/itex]. One-tenth the speed of light is [itex] 1.86\times 10^{4} \frac{miles}{sec} [/itex]. For the first part would I use [itex] v_{x} = v_{x}_{0} + a_{x}t [/itex]? And for the second part I could use [itex] x = x_{0} + v_{x}_{0}t + \frac{1}{2}a_{x}t^{2} [/itex]

Thanks
