Consider an oblique shock wave with a wave angle of 36.87◦. the upstream flow is given by m1 = 3 and p1 = 1 atm. calculate the total pressure behind the shock using a. p0,2/p0,1 from appendix b (the correct way) b. p0,2/p1 from appendix b (the incorrect way) compare the results.

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
