(Answered) A block of mass 600kg initially at rest is pulled to the

Academics

A block of mass 6.00kg initially at rest is pulled to the right by a constant horizontal force with magnitude 12.0N. The coefficient of kinetic friction between the block and the surface is 0.150.

(a) Find the speed of the block after it has moved 3.0m

(b) Suppose the force F is applied at an angle φ. At what angle should the force applied to achieve the largest possible speed after the block has moved 3.0m to the right?
