A jet engine, which delivers a constant thrust Fo, is used to power a plane of constant mass m travelling in a horizontal direction. The plane experiences a drag force given by Fd = -bv, where v is instantaneous velocity and b >0. I f the plane starts from rest at t = , find the velocity v(t) and position x(t).

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 turbojet engine in a wind tunnel receives air at a velocity of U - 100 m/s and a density of p=1 kg/m'. The velocity is uniform and the cross-sectional area of the approaching stream which enters the engine is A-0.1 m² The velocity of the exhaust jet from the engine, however, is not uniform but has a velocity which varies over the cross-section according to 1 - 2U (I-VIR) where the constant U-600 m/s and R is the radius...

1) A motorcycle's engine delivers a top power of 12*sqrt(v), the result being in units of horsepower when the velocity is in miles/hr. Since the motorcycle's velocity isn't changing, most of this power is going toward overcoming air resistance plus a force related to squashing the tires and road (see section 10-10 of the 4th edition of Giancoli or 10-12 of the 3rd edition if you are interested). A) How much work does the engine do in 100 milliseconds at...

4. A test sled has a mass of 400 kg and is acted on by a thrust force of 200,000 N. It also experiences a viscous drag of 1600 V where V is the velocity. Assuming the sled starts from rest, how long before the sled travels 2000m? How fast it is traveling as it passes through this distance? Find the 'terminal velocity' of the sled. How far does it travel before achieving 90% of the terminal velocity? 200,000 N
