a block of mass m is pulled along a horizontal frictionless surface by applying a force at an angle with the horizontal. if the block travels with uniform velocity and has a displacement d and the co efficient of friction is mu, then find the work done by the applied force

as it is frictionless , then v=constant and a=0,
resultant force=0
therefore,
fcostheta-f=0
fcostheta=f=mu mg
W=fcostheta * S=mu mg*S
thank you
