A jet aircraft with mass of 631,405.4 kilograms is flying straight downward. At an instant the plane's engine is producing an downward thrust (force) of 3,329,281.8 Newtons and air resistance is exerting a force of 714,785.5 Newtons upward. What is the acceleration of the plane in m/s2 at that instant? Note: In this problem, we define "down" as positive.

3.) A jet plane is flying with a constant speed along a straight line at an angle of 30° above the horizontal. The plane has a weight W of magnitude 86500 N and its engines provide a forward thrust T of magnitude 103000 N. In addition, the lift force L (directed upwards perpendicular to the wings) and the force R of air resistance (directed opposite the motion) act on the plane. Find L and R. [L = 74900 N; R=...

A 2590-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 2.00 m/s2 and 1.60 s later an upward velocity of 2.46 m/s . At 4.30 s after...

A 21500-kg jet airplane is flying through some high winds. At some point in time, the airplane is pointing due north, while the wind is blowing from the north and east. If the force on the plane from the jet engines is 40700 N due north, and the force from the wind is 15500 N in a direction 70.0 south of west, what will be the magnitude and direction of the plane's acceleration at that moment? Enter the direction of...
