Question

A rocket with a lift off mass 20000 kg is blasted upwards with a net acceleration of 5m/s sq. calculate the initial thrust of the blast. ans 2.96 * 10 to the power 5 newton

Answer 1

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) 

Answer 2

Heya......

Here's your answer...........

Mass of the rocket, m = 20, 000 kg.

Initial acceleration, a = 5 m/s².

Acceleration due to gravity, g = 10 m/s²

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 )

F = 20000 ( 10 + 5 )

F = 20000 * 15

F = 3 * 10^5

Thanks....
