Problem: A flat go-kart track consists of two straightways 100 m long with semicircular ends which have a radius of 25.0 m. A go-kart executes the curved end with a constant tangential acceleration while slowing from 13.1 m/s to 4.2 m/s.
Part A: Determine the magnitude of the total acceleration of the go-kart at the beginning and end of the curve. (Enter your answers to at least two decimal places.)
a) Beginning (m/s2):
b) End (m/s2):
Please show all work and steps I am really trying to learn this for my test.
