A 273.4 kg boulder is pulled with a rope across a field by a strong man. If the man uses a force of 2,424.2 N to cause the boulder to accelerate across the field, The
coefficient of friction is 0.36. How fast does the strong man accelerate the boulder?

Hey.. ♥️♥️ me in solving this question

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

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.
