In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.
A block of mass 6 kg is projected with speed 8 m s−1^{-1}−1 up a line of greatest slope of a rough plane inclined at an angle of 20° 20°\,20° to the horizontal.
The coefficient of friction between the block and the plane is 0.35.
Find the distance the block travels up the plane before it first comes to rest.
Determine whether the block then remains at rest.
