What is the acceleration of a cabinet of mass 45 kilograms if jake and ted push it by applying horizontal force of 25 newtons and 18 newtons respectively in the same direction? (assume a flat, frictionless surface.)

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
