A 2.6 kg block is attached to a horizontal rope that exerts a variable force F_x=(20−5x) Newtons where x is in m. The coefficient of kinetic friction between the block and the floor is 0.25. Initially the block is at rest at x= 0 m.
What is the block's speed when it has been pulled to x = 2.2 m?

A block of mass M is pulled with a rope that exerts a force of a magnitude F, causing it to slide over horizontal ground with kinetic coefficient of friction p (use "mu" when you input your answer). The force is applied at angle theta (use "theta" when you input your answer) above the horizontal shown below. Resolve F into components using the coordinate system shown: F_x, F_y =, Find the sum of the force components in the y-direction acting...
