Imagine that a car is traveling from your left to your right at a constant velocity. Which two actions could the driver take that may be represented as (a) a velocity vector and an acceleration vector both pointing to the right and then (b) changing so the velocity vector points to the right and the acceleration vector points to the left?

(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.

we need to know the time interval during which the force acts. impulse of force = momentum change
