Physiological Effects of High Acceleration: Investigating with a Rocket Train

[courtrigrad]

A rocket-driven sled running on a straight level track is used to investigate the physiological effects of large acceleration on humans. One such sled can attain a speed of 1000 miles/hr in 1.8 sec starting from rest. (a) Assume the acceleration is constant and compare it t o g . (b) What is the distance traveled in this time? For (a) would I use $v_{x} = v_{x}_{0} + a_{x}t$? THe time would be $t = \frac{1.8}{3600}$ hours? Also what does it mean to compare it with g? For the second part I would just use $x = x_{0} + v_{x}_{0}t + \frac{1}{2}a_{x}t^{2}$


Any help is appreciated

Don't forget to convert to SI units. The formulas you're suggesting are correct. To compare the acceleration to g is simple; divide the acceleration by g to get how many times it's greater than g.
