Hi. I have the Marsden an Tromba vector calculus book 6th edition. I was wondering which software was used to create the books graphs. I attach two graphs as an example. Thanks

for one revolution ##A## goes to the right ##2\pi r_1##. For half a revolution ##\pi r_1##. For a given ##\theta## goes to the right ##\theta r_1##?

Hi! I will provide my thinking soon for this question

Hi! My first question: How does he get the equation ##\frac {x_A} {2πr_1} = -\frac {θ} {2π}## ?

Hi! Do you mean this equation ##v_{0B} = v_{0A} + at## where t = 0.628s + 1.39s ?

No. Can you explain?

At point a the value of x=375m and value of t=15s. These values don't satisfy my equation. But they satisfy the equation ##x=50t-375##.

Is the following correct? (for part b)

Hi. My question is for now why the equation of x as a function of time for phase of motion ab is ##x=50t-375##? Shouldn't that be ##x=375+50t##?

Hi. My question is regarding toy car A. If the car moves to the left, is the constant acceleration of ##2.40 \frac {cm} {s^2}## to the left or to the right?

Well, I am wondering how to use this equation... What is ##v_0##? Do I know ##v_0##?

Do you mean this equation: ##x=x_0+v_0 t+\frac {1} {2} at^2## ?

Is it another equation under constant acceleration section of the book? or you mean I should bring a velocity equation (since it is related with position and time) ?

Homework Statement Serway Physics - P2.40 A glider of length 12.4 cm moves on an air track with constant acceleration (Fig P2.39). A time interval of 0.628 s elapses between the moment when its front end passes a fixed point A along the track and the moment when its back end passes this pont...

I don't know. What should I be looking at?
