How do I figure out the acceleration, T=ma?

How do I do this:





One lb. of thrust is the force needed to keep a 1 lb object in a stationary position against the pull of gravity. At launch the space shuttle and its launch rocket and fuel weigh approximately 4,400,000 lb. The two solid rocket boosters each generate about 3,300,000 lb of thrust at launch.





a. What acceleration is imparted to the shuttle and rocket at launch by the booster rockets?





Thrust=mass*acceleration





The answer is 48.3 but I have no idea how they got that.





ThankHow do I figure out the acceleration, T=ma?
T = ma, is just renaming the equation F=ma, Force = Mass x Acceleration.





If you rearrange the equation to get acceleration, you get Force / (divided by) Mass.





The force that they produce is 3 300 000lbs each, so two boosters produces 6 600 000lb force. The mass of the rocket is 4 400 000.





So if you divide 6 600 000 by 4 400 000, you get 1.5..... not 48.3.......How do I figure out the acceleration, T=ma?
0=Mass_of_fuel*acceleration+


+ Mass_of_other_stuff*acceleration_of_grav鈥?


hence we have Mass_of_fuel+Mass_of_other_stuff, acceleration_of_gravity is known, also we know the


value of Mass_of_fuel*acceleration. Now, work out


with these facts...lol.
