Explanation:

Formula to represent thrust is as follows.

F = $\frac{dP}{dt}$

= $\frac{2p}{dt}$

or, p = $\frac{E}{c}$

$\frac{p}{dt} = \frac{W}{c}$

F = $\frac{2IA}{c}$

= $\frac{2 (1000 W/m^{2})(5.5 \times 10^{3} m)^{2}}{3 \times 10^{8} m/s}$

= 201.67 N

Thus, we can conclude that the thrust is 201.67 N.

What effect does a tripling of the net force have upon the acceleration of the object?

dsp73

The formula of net Force is:F = mawhere m is the mass of the objecta is the acceleration of the object
thus, if we triple the net force applied to the object:
3F = maa = 3F / m
The acceleration is also tripled since the force is directly proportional to the acceleration.

Answer:

604.8 kg

Explanation:

Hi there !

d = m/V => m = d×V

V = l×w×h = 10m×12m×4m = 480 m³

m = 1.26kg/m³×480m³ = 604.8 kg

Good luck !
