The angular position of a 0.36-m diameter flywheel is given by $ heta = (2t^3) frac{rad}{s^3}$ a) Find the distance that a particle on the flywheel rim moves over the time interval from t1=2s to t2=5s. b) Find the average angular velocity over the time interval and instantaneous angular velocity at time t1=2s to t2=5s. c) Find the average angular acceleration over the interval and instantaneous angular acceleration at time t1=2s to t2=5s.
A 32-m³ tank contains nitrogen at 22°C and 705 kPa. A release valve is opened allowing some nitrogen to escape until the pressure in the tank drops to 505 kPa. If the temperature at this point is 15°C, determine the amount of nitrogen that has escaped. Round your answer to one decimal place. \Delta m = \underline{\hspace{2cm}} kg
