Question

A rocket with the lift of mass 20000 kg is blasted upwards with an initial acceleration of 5.0 metre per second square. calculate the initial thrust force of the blast.​

Answer 1

Explanation:

Mass of rocket, m=20,000kg

Initial acceleration, a=5m/s

2

g=10m/s

2

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

F=mg+ma=m(a+g)=20000(10+5)=20000×15=3×10

N

F=3×10
