What is the magnitude of the static frictional force acting on the block? A block is at rest on a rough inclined plane and is connected to an object with the same mass as shown. The rope may be considered massless; and the pulley may be considered frictionless. The coefficient of static friction between the block and the plane is µs; and the coefficient of kinetic friction is µk. m m a a) mg sin 0 b) mg cos 0 (c) mg (1 – sin 0) (d) mg (1 – cos 0) ...

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:
