How to find the acceleration of a body in a non inertial frame on the action of friction?
Solution) Use the concept of pseudo force.Multiply the mass of the body of which you need to find the accleration by the accleration of your frame and apply it aganist the direction of accleration. By doing so you are making the frame to become inertial now just add the forces in normal way
