Question

graph is plotted showing the velocity of a car as a function of time. If the graph is a straight line, it means that
the car started at rest
acceleration was constant
acceleration was increasing
velocity was constant​

Answer 1

Explanation:

If the the graph is a straight line parallel to x axis this means that velocity is constant and accelerated is zero.

If the graph is a straight line inclined to x axis at an angle of 45 degrees then acceleration was increasing. Hope this helps
