An aircraft starts at rest and is accelerated for 14.4 seconds, at which time the aircraft launches.

The body, with an initial speed of 2 m/s, began to slide along an inclined plane. For l0s, it passes along an inclined plane of 50 m, and then along a horizontal plane to a stop of 90 m. Assuming the body movement in each of the sections to be equally variable, determine the speed of the body at the end of the inclined plane, acceleration on the inclined and horizontal sections of the path, and average speed along the entire path , body movement time.
