Academics

A car is approaching an intersection and is 17.5 m away. The driver notices that the light turned yellow and accelerates the car with a constant acceleration. One second later the car passes through the intersection and (according to the photo-radar) is moving at 20 m/s.

(a) What is the acceleration of the car? (Express direction in terms of the direction of motion of the car)

(b) What is the initial speed of the car?
