URGENT I cannot express how thankful I am for whoever is nice enough to help me A) A cart loaded with bricks has a total mass of 13.4 kg and is pulled at constant speed by
a rope. The rope is inclined at 21.1° above
the horizontal and the cart moves 17.2 m on
a horizontal floor. The coefficient of kinetic
friction between ground and cart is 0.3.
The acceleration of gravity is 9.8 m/s.
What is the normal force exerted on the
cart by the floor?
Answer in units of N.
B)
How much work is done on the cart by the
rope?
Answer in units of kJ.
C)
Note: The energy change due to friction is a
loss of energy
What is the energy change W, due to fric-
tion?
Answer in units of kJ.

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
