Questions 61-62
The Equation of motion of a rocket in free space can be written where m is the rocket’s mass, v is its velocity, t is time, and u is a constant.
The equation can be solved to give v as a function of m. If the rocket has m = m0 and v = 0 when it starts, what is the solution?
A. u m0/m
B. u exp(m0/m)
C. u sin (m0/m)
D. u tan (m0/m)
E. None of the above
