A small cart weighing 3 kg, pushed by a spring with a coefficient of elasticity of 2.2 × 10⁴ N / m and compressed by 6 cm. Calculate the speed gained by the cart and the path it travels in a horizontal plane knowing that the friction force is 1.5 N​

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

If forces acting on an object are unbalanced. true or false
