Question

a rocket with a lift of mass 20 000kg is blasted upwards with an initial acceleration of 5.0m/s². calculate the initial thurst(force) of the blast

Answer 1

Answer:

Mass of the rocket, m = 20,000 kg Initial acceleration, a = 5 m/s Acceleration due to gravity, g = 10 m/s 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 ) = 20000 × (10 + 5)
