1) A rocket sled running on a straight level track has been used to study the physiological effects of large accelerations on astronauts. One such sled can attain a speed of 408m/sec in 1.6sec. starting from rest.
a) What is the acceleration of the sled, assuming it is constant? Answer in m/s^2.
b) How many g's would you pull? That is, what factor times g=9.80m/s^2 is this?
c) How far does the sled travel in 1.6sec, starting from rest? Answer in meters.© BrainMass Inc. brainmass.com October 9, 2019, 5:40 pm ad1c9bdddf
Please see the attached file.
a) The sled can attain a speed of 408 m/s in 1.6 sec..
Initial velocity = 0
Final velocity = 408 m/s
Time taken = 1.6 sec
Change in velocity = 408 m/s
Acceleration is defined as the change in velocity in 1 sec. (rate of change of velocity).
Now, change of 408 m/s in velocity takes place ...
The problem has been solved using kinematics equations.
