  1. 38*g*cos theta*mu= 180N
    You have one equation in two unknowns.
    You need additional information.
    Is the object's velocity constant? (Zero acceleration?) If so, you can write a second equation.

  2. You cant solve this without knowing more: is the object at constant speed, accelerating, or slowing down?
