Acceleration

=Questions submitted about Acceleration:= toc

Graphing:
1. What is the slope of a velocity vs. time graph?

Concept:
1. What is the formula for acceleration? 2. What is measured in m/s 2 ? 3. What is the difference between v f and v i ? 4. Why do you need the delta (triangle) in front of t in the acceleration equation?

Rearranging Equation:
1. How do you find the change in time when using the acceleration formula? 2. How do you find the initial velocity when using the acceleration formula?

Calculations:
1. What is the acceleration of an object that starts at rest and has a final velocity of 26 m/s and a time of 13 sec? 2. A dog is chasing a mailman and accelerates at a rate of 4 m/s 2. It takes the dog 10 s to reach a final velocity of 30 m/s. What was the initial velocity of the dog? 3. A police car is accelerating at a rate of 2.0 km/hr/s. If its initial velocity is 20 km/hr, what is its velocity after 30 sec?
