A block of mass m is given an initial velocity of u0 at a fixed origin O and it began toslide on a rough horizontal surface. At a position x from O, it has a velocity of v. Takethe magnitude of the acceleration due to gravity to be g and the coefficient of slidingfriction to be μ. (a) Apply Newtonian mechanics and present the equation of motion for the block. the answer i got was a=μg. anyone out there could confirm if i am right? or help me if i am wrong
