Rocket-powered sleds are used to test the responses of humans to acceleration. Starting from rest, one sled can reach a speed of 444 m/s in 1.80 s and can be brought to a stop again in 2.15 s.

a. Calculate the acceleration of the sled when starting, and compare it to the magnitude of the acceleration due to gravity, 9.80 m/s2.

b. Find the acceleration of the sled when braking and compare it to the magnitude of the acceleration due to gravity.

    A rocket test sled accelerates at a constant rate of 15 m/s2 from rest while moving along a straight track. The rocket engine turns off instantly when the sled reaches a speed 30 m/s. The sled then moves freely (acceleration = 0) for a period of 5 s, after which the brakes are automatically applied giving a constant deceleration of -25 m/s2. What is the total time that the sled is moving?

    A rocket, starting from rest, travels straight up with an acceleration of 57.7 m/s2. When the rocket is at a height of 520 m, it produces sound that eventually reaches a ground-based monitoring station directly below. The sound is emitted uniformly in all directions. The monitoring station measures a sound intensity I. Later, the station measures an intensity 1/3I. Assuming that the speed of sound is 343 m/s, find the time that has elapsed between the two measurements.

How high does it rise? Find the velocity of the rocket just before it hits the ground and how long it is in the air?
