Can SOMEONE ANSWER these two questions ? A dog runs from point O to B. The dog reaches A at 2.3 s into the sprint. Then the dog
reaches C at 4.1 s. What is the average velocity of the dog from A to C? A test car travels in a straight line along the -axis. The graph in the figure shows the car’s position as a function of time. At which point is the velocity zero?

Average velocity is given by the change in position divided by the time required for that change.
v = ∆x/∆t = (4 m)/(4.1 s -2.3 s) = 4/1.8 m/s ≈ 2.2 m/s

The instantaneous velocity is zero where the graph is horizontal (no change in position while time marches on—zero slope). Marked points C and G are such points. The appropriate choice is point C.
