Speed-Time Graph

What is the speed at t = 2s
What is the speed at t = 12s
What is the distance travelled by the object from t = 0 to t = 8s (Hints: Area under graph)
Acceleration is the change of speed over time. From the graph above, the object starts from rest (speed=0) and accelerates to a speed of 6 m/s in 4 seconds. The acceleration can found by calculating the gradient.
What is the acceleration of the object at t = 2s
What is the acceleration of the object at t = 6s
Is the object moving at t = 6s
Deceleration is the reverse of acceleration. That means the object is slowing down.
At t = 10s,[br]The gradient [math]m=\frac{6-0}{8-14}=-1[/math][br]The object is
