A jet airplane is in level flight. The mass of the airplane is m = 8870 kg. The plane travels at a constant speed around a circular path of radius R = 9.33 miles and makes one revolution every T = 0.123 hours. What is the magnitude of the lift force acting on the plane? At what angle is the airplane banked?
How much time is neccesary to stop the crate. A block with mass m = 5.5 kg slides down an inclined plane of slope angle 10.9 ° with a constant velocity. It is then projected up the same plane with the initial speed 3.85 m/s. How far up the incline ..
A sailboat is running along a straight course with the wind providing a constant force of 55 lb. The only other force acting on the boat is resistance as the boat moves through the water. The resisting force is numerically equal to five times the boa..
