A wooden block of mass 0.200 kg is given an initial velocity up an aluminum ramp set at a 21 angle above the horizontal. The coefficient of kinetic friction between the wood and the ramp is k = 0.19, and the coefficient of static friction is us 0.25. = Determine the magnitude of the acceleration of the wooden block while it is sliding up the ramp. Give your answer to 2 significant figures.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
