Motion+in+One+Dimension

In class we discussed the relevant equations for describing the motion of an object at a constant acceleration. math Equations \indent for \indent Constant \indent acceleration : \\ \Delta x=\dfrac{1}{2}(v_i+v_f)\Delta t \\ v_f=v_i+a\Delta t\\ \Delta x = v_i\Delta t+\dfrac{1}{2}a(\Delta t)^2\\ v_f^2=v_i^2+2a\Delta x math

Refer back to your notes, we so far have done #1 for both Practice A and B. The solutions to Practice C,D and E will be illustrated below:

Displacement with Constant Acceleration media type="custom" key="6811759"
 * When Maggie applies the brakes of her car, the car slows uniformly from 15.0 m/s to 0.0 m/s in 2.50s. How many meters before a stop sign must she apply her brakes in order to stop at the sign?**

Velocity and Displacement with Constant Acceleration media type="custom" key="6811879"
 * A car with an initial speed of 6.4 m/s accelerates at a uniform rate of 0.92 m/s^2 for 3.6 s. Find the final speed and the displacement of the car during this time.**

Final Velocity After Any Displacement **A car traveling initially at +7.0 m/s accelerates uniformly at the rate of +0.80m/s^2 for a distance of 245m.** **a. What is it's velocity at the end of the acceleration?** **b. What is it's velocity after it accelerates for 125 m?** media type="custom" key="6811995"

The key to solving motion problems is to look for the correct equation to use from the given in your problem. Do the rest of the practice exercises and message me in today's meet for any concerns.
