Text Solution

Verified by Experts

Why does a fast car slow down if its engine is switched off? Answer: When the engine of a car is switched off, then there is no energy available for the engine to oppose the frictional forces. Thus, the engine slows down and eventually comes to rest

A helicopter takes off along the vertical with an acceleration a = 3m//s^(2) and zero initial velocity. In a certain time the pilot switches off the engine. At the point of take off, the sound dies away in a time t_(2) = 30 sec . Determine the velocity of the helicopter at the moment when its engine is switched off assuming that velocity of sound is 320 m/s.

A car can pull a trailer of twice its mass up a certain slope at a maximum speed V. Without the trailer the maximum speed of the car, up the same slope is 2 V. The resistance to the motion is proportional to mass and square of speed. If the car (without trailer) starts to move down the same slope, with its engine shut off, prove that eventually it will acquire a constant speed. Find this speed.

A car can pull a trailer of twice its mass up a certain slope at a maximum speed v=1m//s . Without the trailer the maximum speed of the car up the same slope is 2v . The resistance to the motion is proportinal to mass and square of speed. If the car (without trailer) starts to move down the same slope, with its engine shut off, eventually it will acquire a constant speed v_(t) , then find v_(t)^(2) (in m^(2)//s^(2) )
