Answer:
311,850 N
Explanation:
We can solve the problem by using Newton's second law:
where
F is the net force exerted on the object
m is the mass of the object
a is the acceleration
In this problem, we have
m = 27 kg is the mass
a = 11,550 m/s^2 is the acceleration
Solving for F, we find:
Electromagnetic spectrum
Radio waves
Micro waves
Infrared
Visible lighta
ultraviolet
x ray
gammary
