The engine of a model rocket accelerates the rocket vertically upward for 2.0 s as follows: At t = 0, the rocket's speed is zero; at t = 1.0 s, its speed is 5.0 m/s; and at t = 2.0 s, its speed is 22 m/s. Plot a velocity vs. time graph for this motion, and use the graph to determine each of the following.
(a) the rocket's average acceleration during the 2.0 s interval
m/s2
(b) the instantaneous acceleration of the rocket at t = 1.5 s
m/s2

- A car starts from rest. It accelerates at constant acceleration for 5.0 seconds during which the car covers a distance of 125 m. After that the car continues at that speed for 22 seconds, after which the car slows down at a constant deceleration of – 4.5 m/sec2 until coming to a complete stop. Draw a v vs t, graph, label all the relevant data, and use the graphical method to determine total distance traveled.arrow_forwardYou qualitatively analyzed the motion of a van earlier. Now, using the example of the ball thrown into the air, you can do a more detailed analysis of the van's motion. The table shown here includes the time and position data, with one worked example for finding acceleration.
