Hey guys i need help with a physics problem anyone out there can help. i just need help figuring it out.

here it is
a 1000kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 16s, then the motor stops. The rocket altitude 20's after launch is 5100 m . you can ignore any effects of air resistance.

a.What was the rocket's acceleration during the first 16s?
