A sprinter explodes out of the starting block with an acceleration of +2.3 m/s^2, which she sustains for 1.2s. Then, her acceleration drops to zero for the rest of the race. What is her velocity (a) at t=1.2s and (b) at the end of the race?

A sprinter explodes out of the starting block with an acceleration of $+2.3 \mathrm{m} / \mathrm{s}^{2}$ , which she sustains for 1.2 $\mathrm{s}$ . Then, her acceleration drops to zero for the rest of the race. What is her velocity $(\mathrm{a})$ at $t=1.2 \mathrm{s}$ and (b) at the end of the race?
