Please help me For a velocity versus time graph how do you know what the velocity is at a certain time? How do you know the acceleration at a certain time?

Explained below

Explanation:

For a velocity time graph, the y - axis will represent velocity while the x - axis will represent time.

Now, to calculate velocity at a certain time t, we will draw a perpendicular line from the time on the x-axis to the graph line and trace the horizontal line from that point to the y-axis which will give the corresponding velocity at that time.

Now, for the acceleration at a time t. After getting the velocity like explained above, we now divide the velocity by the time.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

c) up

hope this
