A projectile of mass .5 kg is fired with an initial speed of 10 m/s at an angle of 60 degrees above the horizontal. The potential energy of the projectile-Earth system when the projectile is at its highest (relative to the potential energy when the projectile is at ground level) is: 25 J, 18.75 J, 12.5 J, 6.25 J, or none of these

PROBLEM 3. Consider the outlet port 1 with mass flow rate $M_1^{out}$ shown in the system described below. $M_1^{in}$ $M_2^{in}$ MV System $M_1^{out}$ $M_2^{out}$ Calculate the amount of mass removed from the volume though port 1 in the lapse of time between 2 and 4 minutes under the following conditions: a) The flow rate is given by $M_1^{out}(t) = 0.017$ in units of g/s. b) The flow rate is given by $M_1^{out}(t) = 0.017t$ in units of g/s where $t$ is in seconds. c) The flow rate is given by $M_1^{out}(t) = \frac{0.017}{0.1+t}$ in units of g/s where $t$ is in seconds. Hint: Make sure to use the correct sign for the outlet flow when calculating the total amount removed.
