2X48
Section B]
5. What are the uses of a velocity-time graph?
Soha body have zero velocity and finite acceleration?​

Answer 1

23.the rate of change of velocity per unit of time is called acceleration

5.Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. They can be used to show acceleration and to work out displacement.Yes, a body can have zero velocity but finite acceleration.
