I need help with the question below: Two children are arguing over a toy. One child pulls on it with a force of 15 N [S45 o E] and the other child pulls on it with a force of 20 N [N45 o E]. Using these components, calculate the acceleration of the toy if it has a mass of 2.5 kg.

Thank you in advance

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.
