An aeroplane needs to reach a speed of 324 km/hr before it can take off. It starts from rest and the engine of aeroplane produces a constant acceleration. If it spends 30 s on the runway then the minimum required runway length is -

An aeroplane has a run of 500 m to take off from runway. It starts from rest and moves with constant acceleration to cover the runway in 30 s. What is the velocity of the aeroplane at the take off?

An aeroplane has a run of 500 m to take off from the runway. It starts from rest and moves with constant acceleration to cover the runway in 30 sec. What is the velocity of the aeroplane at the take off?

An aeroplane takes off the ground after covering distance of 800 m of runway in 16 s. Its acceleration will be

Starting from rest a fan takes 5 s to attain the maximum speed of 400 rpm. Assuming constant acceleration, the time taken by the fan in attaining half the maximum speed is

An aeroplane requires a speed of 72 kmph for a take off with 150m run on the ground. The mass of the plane is 1500kg and the coefficient of friction between the aeroplane and the ground is 0.4. Assuming that the aeroplane acceleration uniformly during take off, find the minimum force exerted by the engine of the aeroplane for take off.

In an aircraft carrier warship the runway is a 20 m long strip inclined at theta = 20^(@) to the horizontal. The launcher is effectively a large spring that pushes an aircraft of mass m = 2000 kg for first 5 m of the 20 m long runway. The jet engine of the plane produces a constant thrust of 6 xx 10^(4) N for the entire length of the runway. The plane needs to have a speed of 180 kph at the end of the runway. Neglect air resistance and calculate the spring constant of the launcher. [ sin 20^(@) = 0.3 and g = 10 m//s^(2) ]
