# Answer on Mechanics | Relativity Question for graham jones

Question #54967

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?
