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) ]

An automobile starts from rest and accelerates unifomly for 30 second to a speed of 72 km h^(-1) . It then moves with a uniform veocit and it is finally brought to rest in 50 m with a constant retardation. If the total distance travelled is 950 m , find the accleration, the retaradation and total time taken.

An automobile can accelerate or decelerated at a maximum value of 5m//s^(2) and can attain a maximum speed of 90 km hr. It it starts from rest. What is the shortest time in which can travel 80 metre. If it is comes to rest at the end of the 80 metre run ?

An aeroplane requires for take off a speed of 80 km//h the run on the ground being 100 m The mass of aeroplane is 10^(4) kg and ground is 0.2 What is the maximum force required by the engine of the plane for take off ?

Two motor cars start from A simultaneously & reach B after 2 hour. The first car travelled half the distance at a speed of v_(1)=30 km hr^(-1) & the other half at a speed of v_(2)=60 km hr^(-1) . The second car covered the entire with a constant acceleration. At what instant of time, were the speeds of both the vehicles same? Will one of them overtake the other enroute?

Airport authority has made the regulation that maximum allowable intensity level detected by a microphone situated at the end of 1630 m long runway can be 100 dB. An aeroplane when flying at a height of 200 m produces an intensity level of 100 dB on ground. while taking off, this aeroplane makes an angle of 30^@ with horizontal. Find the maximum distance this aeroplane can cover on the runway, so that the regulation are not violated (assume no reflection).

A motorcyclist starts from rest and accelerates to a speed of 60km/hr in 50s, on a straight road. Calculate the distance covered by the motorcyclist in this time.

A car of mass 900 kg accelerates uniformly from rest to a speed of 60 km/h in a time of 2 s when traveling on a level road. If there is a constant resistance to motion of 20 N. Find the maximum power ( in kW) of the engine.
