consider a hypersonic missile flying at mach 8 at an altitude of 6 km. the nose of the missile is blunt. calculate the pressure at the stagnation point on the nose. 2·(20 pts) show that the thermodynamic quantities across a shock can be related as e2-e1 = hint: the continuity, momentum, and energy equations across a normal shock wave are (v1-v2) . 2 2 3 - (20 pts) ergent-divergent nozzle with an exit-to-throat area ratio of 1.616 has exit and reservoir pressure atm reenectively in addition, the reservoir temperature is 288 k and the throat are equal to 0947 and 1 0 reg

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
