Sahay Sir > Question Answers > MTG NEET Physics > Part 1 > Chapter 7 - Circular Motion > A toy car starts from rest along the circular track of radius R on a horizontal board with a tangential acceleration a0. At the same instant, board starts from rest and accelerate upward with an acceleration a1. The coefficient of friction between board and car is u. The speed of the car relative to board at which it will skin in R^2(u^n (g + a1)^2 – a0^2) ^1/4. Find the value of n.
