Question 805290
The space shuttle could blast off and reach an altitude of 2.0km in 15.0s. Assuming that the acceleration was uniform,what is the acceleration of the shuttle? What was its velocity at this point?
------------
s = at^2/2
2000 = a*15^2/2
a = 4000/225 =~ 17.778 m/sec/sec
-------------
v = at = 15*17.778
v = 266.67 m/sec
