Question

In the previous question, Terry is "driving" his toy car back and forth on a track, making it go to the right (positive x-axis) some times and to the left (negative x-axis) at other times. Match the following combinations of velocity and acceleration to the appropriate outcome. The car's velocity and acceleration both have negative values. The car's velocity and acceleration both have positive values. The car's velocity is negative, but its acceleration is positive. The car's velocity is positive, but its acceleration is negative. The car's speed is increasing while it travels to the right. The car's speed is decreasing while it travels to the right. The car's speed is decreasing while it travels to the left. The car's speed is increasing while it travels to the left.

Explanation / Answer

Here ,

for the speed is increasing and it is travelling to the right ,

the velocity and acceleration both must be positive

>> the correct option is 2

------------------------------------------

the car's speed is decreasing and it is travelling to right

the velocity must be positive , acceleration is negative

the correct option is 4)

-------------------------------------

the car's speed is decreasing and it is travelling to the left

the velocity is negative and the acceleration is positive

the correct option is 3)

--------------------------

here , the acceleration and velocity are both negative
