Question

. A rocket with a lift-off mass 20,000 kg is blasted upwards with an initial acceleration of 5.0 m. Calculate the initial thrust (force) of the blast.​

Answer 1

Explanation:

Initial acceleration, a= 5 m/s2

Acceleration due to gravity, g=

Using Newton's second law of motion, the net force (thrust) acting on the rocket is given by the relation:

F- mg = ma

F= m (g + a
