Homework 1. A skg block, resting on a rough horizontal
surface is connected by a light in extensible
String over a light frictionless pulley to
second block of mass
mass 3kg hanging vertically.
An applied force of f is acting
the
block as shown in the diagram, and
the study coefficient Of kinetic frictia
between the sky and the surface is
Qa. The sto block accelerates to the
boot.
5 kg
a) Calculate the acceleration of the blooks.
b) Calculate the tension T.​

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
