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 224 m>s1500 mi>h2 in 0.900 s. (a) Compute the acceleration in m>s 2 , assuming that it is constant. (b) What is the ratio of this acceleration to that of a freely falling body (g)

Explanation:

Given data

Final Speed=224 m/s

initial speed=0 m/s

Distance=1070m

Time=0.900s

For Part (a) Acceleration

This is analysis model for particle under constant acceleration

In order to calculate the acceleration we will use following equations

Substitute the given values

For Part (B) the ratio of this acceleration to that of a freely falling body (g)

The ratio between both acceleration is given below as:
