A cubic block of mass m is sliding down on an inclined plane at 60^ with an acceleration of g 2 , the value of coefficient of kinetic friction is

Options

  1. A3 -1
  2. B3 2
  3. C2 3
  4. D1- 3 2

Correct answer

A. 3 -1

Step-by-step solution

mg 60^ - mg 60^ = ma g 60- g 60= g 2 3 2 - 2 = 1 2 = 3 -1
