Question

A body is sliding down a rough inclined plane which makes an angle of 30 degree with the horizontal. If the coefficient of friction is 0.26, Determine the acceleration in ms-2.
​

Answer 1

Answer:

2.79 ms-2

Explanation:

if m is the mass of the body

mg sin30° is the downward force

apply F=ma,

mg sin30° -F= ma (F is friction)

mg/2 -0.26 mg cos 30° =ma ( friction is the multiplication of coefficient of friction and normal reaction)

g/2- 0.26 g√3/2= a

2.79ms-2 =a (not sure abt simplification)
