The shape of the acceleration - time graph will be linear.
The acceleration of an object is the rate of change of velocity with time.
a = Δv/Δt
where;
When the velocity of the object is constant, the acceleration of the object becomes zero.
When the velocity of the object is uniform, the object accelerates at a constant rate.
If the truck accelerates at a constant rate from the motion detector, the shape of the graph will be linear.
Thus, the shape of the acceleration - time graph will be linear.
