Transcribed Image Text:Task 1
A rocket's mass m(t) is a function of time t because it decreases as it burns fuel. Newton's law states
that the equation of motion for a rocket in flight is given by:
dv
m(t) = T - m(t)g
dt
where T is the rocket's thrust, g is the gravitational acceleration. Hence, the velocity of the rocket can
be calculated as:
The mass follows the relationship:
T - m(t)g
m(t)
v(t) = [¹7
m(t) = mo
dt
rt
(1-7²)
b
where mo is the rocket's initial mass, b is the burn time, and r is the fraction of the total mass accounted
for by the fuel.
