Answer:
(a). The speed of car will increases.
(b). The speed of car will decreases.
Explanation:
Given that,
A car is traveling from your left to your right at a constant velocity.
We need to find two actions could the driver take
Using given data
(a). If the velocity and acceleration of car to the right
It means the velocity and acceleration of car is in same direction then the speed of car will increases.
(b). If the velocity to the right and the acceleration to the left
It means the velocity and acceleration of car is in opposite direction then the speed of car will decreases.
Hence, (a). The speed of car will increases.
(b). The speed of car will decreases.
