Question

A jet engine pushes out 50kg of gas every second at a velocity of 150m/s

a) what thrust (force)does the engine produce?
b) If the engine pushed out twice the mass of gas at half the velocity, what would the thrust (force) be?

*will mark the brainliest answer*

Answer 1

To find the thrust we will have to find the acceleration of the gas

as initial velocity is 0 as the is in rest state

final velocity is v = 150m/s
time is 1 sec


v=u+at

150=0+a(1)

a=150

force = mass * acceleration

force=50*150
f=7500 N

in the second part the acceleration will be half and mass will be twice

thus no effect on force applied

f=7500

Answer 2

a. 7500 newton
b. 7500 newton no change will there
