A rocket driven sled runnung on a straight level track has been used to study physiological effects on large accelerations on astronauts. One such sled can attain a speed of 361 m/s in 1.7 s starting from rest. What is the acceleration of the sled, assuming it is constant? Answer in units of meters per seconds squared(m/s^2)

How far does the sled travel in 1.7s, starting from rest? Answer in units of m.

Simple:
361 m/s divided by 1.7 s = 212.4 m/s/s which is the same as m/s^2
That's 21.6 g's btw

Just divide 361 m/s by 1.7 s and you'll have your answer - because the units will be correct.

take 361/1.7

361(m/sec)/1.7sec = acceleration
= 212.35m/sec*sec
