Problem a flat go-kart track consists of two straightways, Ask an Expert

Academics

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.
