What does the slope represent of this graph?

A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure below. The length of the arc ABC is 260 m, and the car completes the turn in 40.0 s. I need to find the acceleration at a point 35 degrees below the horizontal in terms of vectors I...

Find the angular accleration of a thin ring of radius 0.300 m and 1.50 kg mass if a constant 20.0 N force acts on a string wrapped around the ring's circumference. Find the angular velocity of the ring after 5.00 seconds.

When using the Speed= distance/time how would one go about plugging numbers in if the question in a wheel has the diameter of 7 and rotates 1700 revolution per minute. I know you use the Circunfrace which is 14pie then what do you do about the 1700 revolutions; where does that fit in? If any one...

Can the derivative of acceleration be subsituted for a in f=ma?
