Chapter 2, Problem 2/163 As part of an unmanned-autonomous-vehicle (UAV) demonstration, an unmanned vehicle B launches a projectile A from the position shown while traveling at a constant speed of 32 km/h. The projectile is launched with a speed of 66 m/s relative to the vehicle. At what launch angle a should the projectile be fired to ensure that it strikes a target at C? Compare your answer with that for the case where the vehicle is stationary. Note that...

Chapter 2, Practice Problem 2/090 Your answer is partially correct. Try again. Airplane A is flying north with a horizontal velocity of 514 km/h and is accelerating in its northward direction at the rate of 2.1 km/h each second. Airplane B is flying southwest at the same altitude with a velocity of 515 km/h which is decreasing at the rate of 2.3 km/h each second. Determine the acceleration B/A which B appears to have to an observer in A and...
