Question

Help with multiple choice and if possible short answer. Please&ThankYou!! Analysis 1. What is the physical traveling down an incline? meaning of the slope of your graph of velocity vereus time for the cart 2. What is the physical meaning of the vertical intercept of the graph 3. Compare the slope of your velocity versus time graph groups. What factors affect whether to the alope of the graphs from other r or not your value is greater than or less than theirs? 4. What is the physical meaning of the slope of the graph from the position versus & graph? 5. What is the physical meaning of the vertical intercept of the graph? 6 How does the slope of a velocity versus time graph compare to the slope of a position versus e graph? what relationship exists between the two slopes? Synthesis Questions Use available resources to help you answer the following questions. 1. In the above analysis questions the following equations should have been derived: x = xo + vot + at 2 and u = vo + at. Do the versions you derived include a term, why or why not? 2. Another kinematic equation is: x 2 (vo + v). Use this equation in combination with one of the equations that you derived from this lab to derive a fourth equation: u"- +2ax

Explanation / Answer

1. (B) velocity (v = dx/dt)

2. (A) acceleration ( a = dv/dt)

3. (E) displacement ( x = integral of v dt )

4. (B) change in velocity ( dv = a dt)

5. d = v0 t + a t^2 / 2

12 = 0 + a (2^2 / 2)

a = 6 m/s^2

Ans(D)

6. v =v0 + a t

10 = 0 + 5 t

t = 2 sec

Ans(C)
