Answer:
a = 45 m/s/s
Explanation:
As we know that total mass of the rocket is

total mass of the fuel is given as

all the fuel is burnt in 15 s
so rate of the fuel burning is given as


now the thrust force on the rocket is given as


so we have

so we have


now acceleration is rate of change in velocity

so acceleration at t = 15 s
