I just need help getting started with this question. A 1350.0 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 10.2 s, then the motor stops. The rocket altitude 26.9 s after launch is 2210.0 m. You can ignore any effects of air resistance. What was the rocket's acceleration during the first 10.2 s? total distance is 2210.0 m acceleration during 10.2 s and 26.9 s is -9.81 m/s^2 the acceleration during t=0 s and t=10.2 s is cst.
