The figure below shows the velocity versus time curve for a rocket in outer space where the only significant force on the rocket is
from its engines. It can be shown that the mass M(t) (in slugs) of the rocket at time t seconds satisfies the equation
M(t) =
T
PARTIR
where T is the thrust (in lb) of the rocket’s engines and v is the velocity (in ft/s) of the rocket. The thrust of the first stage of certain
rocket is T = 7725667 lb. Use this value of 7 and the line segment in the figure below to estimate the mass of the rocket at time
t = 100.
