A car is waiting at an intersection. When the traffic light turns green, the car starts

moving. After some time the car comes to rest at another traffic light. The figure

below shows the velocity of the car as a function of time.

One can clearly identify three different stages of this motion.

What is the acceleration of the car in the first stage?

$3\mathrm{.}00\frac{m}{s^{{?}^{{?}^{?}}}}2$

You are correct.

$-2\mathrm{.}75\frac{m}{s^{{?}^{{?}^{?}}}}2$

You are correct.
