Question: the acceleration of a rocket traveling upward is given by...

The acceleration of a rocket traveling upward is given by a = (5 + 0.02s) m/s2, where s is in meters.(Figure 1). Initially, v = 0 and s = 0 when t = 0. Determine the time needed for the rocket to reach an altitude of s = 170 m . The answer is not 7.3 s
