How does speed and acceleration affect the motion of a car

Step-by-step explanation:

An object accelerates when its speed changes or its direction of motion changes or both. ... If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force

Step-by-step explanation:

Because a change in velocity can be either a change in how fast samething is moving.. an object changes it speed it direction or both ...if the speed is increasing the car has positive acceleration,when the car slow down the speed decreases

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
