A car had a change in velocity of 40 m/s with an acceleration of 5 m/s2. How long did it take this acceleration to occur? 40 m/s = ∆v. 5 m/s2 = a? = t. a = vf - vi / t. 5 = 40/ t. t = 8s . Title: Motion Problems – Speed, Velocity and Momentum problems …

4. An automobile starting at rest (0 ft/sec) increases to a velocity of 91 ft/sec in 7 seconds. What was the acceleration of this vehicle? 5. An object falls from a skyscraper and hits the ground after 5 seconds. The acceleration of this object due to gravity was 9.8 m/s2. What was the change in velocity of this object? 6.

How does the velocity of the car change as it moves down the ramp? Make a graph to compare speed vs. position of the car. Using the Graph to Predict Velocity: Choose a spot on the ramp where you did not measure the velocity of the car. Use the graph to find the predicted velocity of the car at that distance. Record.

What is the object’s change in velocity between t = 0 s and t = 4 s? Equations of Motion for Uniform Acceleration. Uniform or Constant Acceleration is acceleration that does not change with time. The velocity-time graph of a body experiencing such motion is a straight line. The following equations are valid only for such cases:

12.Use the tools of your data collection software to find the the change in velocity during the collision with the spring bumper and record it in Table 1. The coordinates tool delta function can be very helpful. Make sure to account for the change in sign of the velocity. For example, going from +0.5 m/s to -0.5 m/s is a change of -1 m/s.

change in velocity over time. Motion – an object changing position or distance in time. Rate of Change – amount of time it takes to change position or motion . Inertia - tendency of a still object to stay still or miving object to keep moving unless acted on by an unbalanced force.

3 Ways to Calculate Velocity - wikiHow
Show below how you would find the vector representing the change in velocity between the times 1 sec and 2 sec in the diagram above. (Hint: remember that the change in velocity is the final velocity minus the initial velocity, and the vector difference is the same as the sum of one vector and the negative of the other vector.)
