A650 kg airplane must reach its takeoff speed while traveling down a 61.0 m long runway. the pilot starts the plane from rest, and by the end of the runway he has reached the takeoff speed of 29.0 m/s. to the nearest newton, what net force must act on the plane? hint: there are multiple ways you could go about solving this problem.

Force in the plane will be 4488.09 N

Explanation:

We have given mass of the airplane m = 650 kg

Length of the runway S = 61 m

As the plane starts from rest so initial; velocity u = 0 m/sec

Final velocity of airplane v = 29 m/sec

From first equation of motion v = u+at

29 = 0+at

at = 29

From second equation of motion

Now using at =29

t = 4.20 sec

So

According to second law of motion F= ma

So force F = 650×6.9 = 4488.09 N

the correct answer is blue and green.

a visible spectrum is electromagnetic spectrum color that can be seen by a normal human being by a single wavelength of light. the visible light spectrum is the range of wavelengths that make up visible light. the visible light spectrum passes through a prism enabling the rainbow reveals all the colors in the spectrum. these range from red, orange, yellow, green, blue and violet.

true

hope this . : d
