For the answer to the question above, <span>at the end, the KE = 1/2mv^2 = (1/2)(2000)(2^2) = 4000 J This must equal the net work acting on the car. W=Fd The net force is 1140-950= 190N. so, d=W/F = 4000/190 = 21.05 m
I hope my answer helped you.</span>

I looked it up for you to help you out and it said it was d
Answer: f = 392 hz
v = 343 m/s
wavelength = 343/392 = 0.875 m
hope this helped!

Answer:
50 degrees
Explanation:
Usually in physics in solving such questions refractive index of air is taken as 1.00 (n=1.00) by assuming that air is a vacuum. Hence, the light ray passes from water to air at an angle of incident of 40 degrees, it means that it has angle of 50 degrees to the normal line.
