A 20kg block is on an inclined plane that makes an angle of 40° with the horizontal. The coefficient of static friction is 0.4 and the coefficient of kinetic friction is 0.3 determine :a) whether the block will start sliding down the plane
b)if it slide, calculate it's acceleration
Take g=10m/s² sin 40°=0.642,cos 40°=0.766?
