A rocket is traveling horizontally over thesurface of Mars as indicated in the figure to theright, moving at a speed VR = 100 m/s relativeto the surface. The exhaust gas being expelledfrom the rocket is traveling at a speed of VG/R =30 m/s, relative to the rocket.VRVG/R(a) Determine the velocity (speed and direction) of the exhaust gas relative to the ground(i.e., the absolute velocity of the exhaust) at this instant.(b) If the exhaust gas temperature is TG = 3500 K, and the exhaust nozzle area is A = 2 m²,determine the mass flow rate of gas exiting the rocket. Assume a Mars atmosphericpressure Patm,Mars = 600 Pa, and a gas constant RMars = 188 J/(kg k).

Homework A circular jet of water at 20°C Implnges on the vane shown In flgure. The Incident jet has a velocity of 25 m/s and a dlameter of 200 mm. The vane divides the Incident jet equally, and the jet exits the vane as two jets, each making an angle of 200 with the Incoming Jet. (a) Determine the force on the vane when the vane 200 mm 25 m/s- 20° V. Incident jet Moving vane Is moving at a speed of 15 m/s In the same directlon as that of the Incident jet. (b) Determine the force on the vane when the vane Is moving at a speed of 15 m/s In the opposite dlirection to that of the Incident jet. Assume water at 20°C.
A cart is moving at a constant absolute velocity V-›cart = 3 km/h to the right. A high-speed jet of water at an absolute velocity of V-›jet = 15 km/h to the right strikes the back of the car. The relative velocity of the water is (a) 0 km/h (b) 3 km/h (c) 12 km/h (d ) 15 km/h (e) 18 km/h
The figure shows a plate that is driven by a vertical jet. The plate has a mass (m) of 25.0 kg. By the time shown, the plate is suspended 2.0 m above the jet outlet (H) and moves upwards with a vertical speed of 5.0 m/s (U). For the instant shown, determine the acceleration on the plate if the output area in the jet is 5.0 x10-3 m2 and its output speed is 15.0 m/s (Vj).

Explain the physical meaning of each of the terms in Equation 3. The momentum equations for a rotating shallow homogeneous fluid with a free upper surface (i.e. the shallow water equations) are equation 1 & 2. where u(x, y,t), v(x, y,t) are the velocities on the free surface, and h(x, y,t) is the depthof the free surface.
In the figure, the velocity of the water jet coming out of the 2.5 cm stationary fountain is given as 16 m / s to the right. What is the Frx force (N) that the water jet exerts on the car in the horizontal direction at the moment the speed of the car is 10 m / s to the right?
