The velocity-time graph for the motion is shown above. Find (i) the distance travelled by the elevator, (ii) the acceleration during the first stage and the deceleration during the third stage. A cyclist starts from rest at point A and moves in a straight line with acceleration 0.5 m s...
If the acceleration is constant, we know that the object will always gain (or lose) the same amount of speed in the same time period. Then, this calculation for acceleration is completely accurate at all times t for a constant acceleration. Part of the magnitude of the acceleration vector ...
To simplify calculations we take acceleration to be constant, so that a¯=aa¯=a at all times. We also take initial time to be zero. Initial position and velocity are given a subscript 0; final values have no subscript. Thus, {Δt=tΔx=x−x0Δv=v−v0⎩...
If we choose to let the initial moment in time equal 0, then we can plot points for this object on a velocity–time graph as follows. We see that over time, the velocity of our object increases. And we are told this increase happens at a constant rate. Therefore, the object accelerate...

Consider the graph of the velocity versus time. Identify the time (or times) at which the instantaneous acceleration is zero. An object moves in the +x-direction at a speed of 34 m/s. As it passes through the origin, it starts to experience a constant acceleration of 3.0 m/s^2 in ...
