6. An airplane of mass 80,000 kg travelling at 80 m/s lands on the runway. The plane comes to rest over a distance of 1200 m. The plane uses two mechanisms of force to come to rest. One is the reverse thrust of the engines. The other is the brakes between the tires and the runway. If the thrust of the engines provides twice the force as the brakes, determine the force of each of these forces. (20 points)

A plane lands with a velocity of 120 m/s and accelerates at a maximum rate of -4.0 m/s2.(a)From the instant the plane touches the runway, what is the minimum time needed before it can come to rest?(b)What is the minimum distance the plane needs to land?

To take off from the ground, an airplane must reach a sufficiently high speed. The velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity. 1.) A plane accelerates from rest at a constant rate of 5.00m/s2 along a runway that is 1800m long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time tTO needed to take off?...

3. A 180-Ib person jumps out of an airplane with initial upward velocity of 5 ft/s at a height of 3000 ft (assuming the air resistance is proportional to its falling speed). The air resists the body's motion with a force of 2 lb for each ft/s of speed. Assuming the constant gravity is 32 ft/s2. 1. find its velocity v = v(t) 2. find its terminal velocity 3. find the distance of falling x = x(t) 4. find the...

2. An airplane is rolling at speed of 10 m/s when it turns onto a runway from the boarding area. The plane's engines fire up, resulting in a constant acceleration of 1.5 m/s2. The runway has a length of 2000 m. a) How fast is the plane travelling when it reaches the end of the runway The plane reaches a speed of 250 m/s soon after takeoff in a windless situation and maintains that speed in a due north direction....
