Homework Statement
A Hot Wheels car, whose mass is 200g is hauling a mass block of 150g along a flat table surface
with a string as shown in the graph below. Assume the car and the attached mass is moving with
an initial velocity of 1.7 m/s. A student predicts that the car will travel a maximum distance of
42 cm. Is this a reasonable prediction? Explain fully.

Homework Equations
KE = 1/2mV2
[tex]\Sigma[/tex]F = mgcos[tex]\theta[/tex]s
The Attempt at a Solution
I know that the formulas listed above are needed to solve this. After plugging in:
m = .350, v = 1.7, I get KE = .505 J
But where do I go from here to get distance? What would be theta be in this instance?
I have this formula KEf = KF0 + [tex]\Sigma[/tex]F = mgcos[tex]\theta[/tex]s, but I'm not sure what to use for theta?
I've attached the image to this post
Thanks for any hints!
