The rocket-driven sled sonic wind no. 2, used for investigating the physiological effects of large accelerations, runs on a straight, level track 1070 m (3500 ft) long. starting from rest, it can reach a speed of in 0.900 s. (a) compute the acceleration in assuming that it is constant. (b) what is the ratio of this acceleration to that of a freely falling body (g)? (c) what distance is covered in 0.900 s? (d) a magazine article states that at the end of a certain run, the speed of the sled decreased from to zero in 1.40 s and that during this time the magnitude of the acceleration was greater than 40g. are these figures consistent?

An aircraft performs a maneuver called an "aileron roll." during this maneuver, the plane turns like a screw as it maintains a straight flight path, which sets the wings in circular motion. if it takes it 35 s to complete the circle and the wingspan of the plane is 11 m, what is the acceleration of the wing tip
