An airplane accelerates at 3 m/s2. the takeoff speed for this plane will be 65 m/s. how long does the plane accelerate?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Multiply or divide to make this english distance conversion. 174 inches = feet (14.5, 58, 2,088, 23)
