The space shuttle fleet was designed with two booster stages

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, 470,000 pound-mass, what is the acceleration of the spacecraft in miles per hour squared [m/h^2] We go out to sunbathe on a warm summer day. If we soak up 100 British thermal units [BTU] per hour of energy, how much will the temperature of a 132 pound-mass person increase in 2 hours, in units of degrees Celsius? We can assume that since our bodies are mostly water, they have the same specific heat as water. (The specific heat of water is 4.18 joules per gram degree Celsius [J/g middot degree C]) The equation for thermal energy is Q = m C_p Delta T, where Q is the quantity of heat transferred to the object, m is the mass of the object, C_p is the specific heat of the object, and Delta T is the resulting change in temperature of the object that results from the heat transfer.

Solution

1 pound = 0.453592 kgs.

Hence 44,70,000 pounds = 4470000(0.453592)

= 2027556.24 kg.

Hence acceleration = 5.25/2027556.24 metres/hour ^2

=0.000621371/2027556.24

=3.0464x10^-10
