A jet airplane in level flight has a mass of 8.61 x 104 kg, and the two wings have an estimated total area of 88.0 m2 (a) What is the pressure difference between the lower and upper surfaces of the wings? Pa (b) If the speed of air under the wings is 233 m/s, what is the speed of the air over the wings? Assume air has a density of 1.29 kg/m3 m/s (c) Explain why all aircraft have a...
A 3-kg ball has a momentum of 43 kg m/s. What is the ball's speed?! Please report answer to two significant figures and use the abbreviated form of the unit. Answer:
atom is 6.64 x 10-27 kg. (a) the escape speed from Earth, 1.12 x 104 m/s (b) the escape speed from Mercury, 4.27 x 103m/s Your response differs from the correct answer by more than 10%. Double check your calculations. K
A 1.5 g particle has momentum 4.0×105 kg⋅m/s What is the particle's speed? Express your answer using two significant figures.
2. A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had. e. three times the mass and was moving with one-half the speed? f. three times the mass and was moving with twice the speed?
Q1 A small object with a momentum of magnitude 2.71 kg m/s approaches head-on a large object at rest. The small object bounces straight back with a momentum of magnitude 6.19 kg m/s. What is the magnitude of the small object's momentum change in kg m/s? Q2 A force acts on a 4.708 kg mass as follows: the force starts at zero and rises to 60.334 N linearly in 2.24 seconds, it remains at 60.334 N for another 5.756 seconds,...
