spacecraft includes the Endeavour shuttle, its external rockets, its fuel tank, and its fuel. The total mass of
the entire spacecraft changed as fuel was used. The model below shows the predicted mass m, in
thousands of kilograms, of the entire spacecraft t seconds after the launch.
m = 2,050 - 9.75t, Osts 120
According to the given model, what was the predicted mass, in thousands of kilograms, of the entire
