Question: The 2 - kg block is subjected to a force having a constant direction and a magnitude F = ( 3 0 0 s 2

The 2-kg block is subjected to a force having a constant
direction and a magnitude F=(300s2) Newton, where s is
in meters. When s=4m, the block is moving to the left
with a speed of 8ms. Determine its speed when s=12m.
The coefficient of kinetic friction between the block and the
ground is k=0.25.
