(Aeronautics) The initial acceleration, a, of a rocket fired from Earth, with an initial thrust, T, is given by this formula:

a is the initial acceleration.

T is the thrust in Newtons.

m is the mass in kg.

g is the acceleration caused by gravity in m/s2.

a. Determine the units of the initial acceleration by calculating the units resulting from the right side of the equation. (Hint: As listed in Table, a Newton is N = kg-m/s2.)

b. Determine the initial acceleration of a rocket having a mass of 5 × 104 kg and an initial thrust of 6 × 105 Newtons. The value of g is 9.81 m/s2.
