please solve it

of the incline and is connected to the motor using a light string. The motor is switched on and it slowly hauls block B through a distance L = 2.0 meter along the incline. Calculate the work done by the string tension force on the wedge plus motor system. All surfaces are frictionless. AK B Q. 93. A triangular wedge (A) has inclined surface making an angle = 37 to the horizontal. A motor (M) is fixed at the top of the wedge. Mass of the wedge plus motor system is 3m. A small block (B) of mass m= 1kg is placed at the bottom
