The space shuttle fleet was designed with two booster stages. If the first stage provides a thrust of 5.25 ​Mega-newtons and the space shuttle has a mass of 4,530,000 ​pound-mass, what is the acceleration of the spacecraft in miles per hour​ squared?

Answer 1

1000 poundmass=453kg

F=ma
a=f/m=5.24E6/(4.53E6lb*453kg/1E3lb

a= 5.24/4.53*453 *1E(6-6+3) m/s
= 2.55m/s
= 2.33m/s* 2.23(mile/hr /m/s)
= 5.20mile/hr

check all this math.

Answer 2

Something seems to be missing since it isn't the answer :/

i think you did some rounding early because by the end of the equation you have to round the answer to three significant figures

Answer 3

check it, you might be right.
