The air resistance, R newtons, to the motion of a train varies as the square root of its speed, yms-1.
If the resistance is 3 600 newtons when the speed is 16 m s-1, calculate R when v = 64.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

yes ok                                            

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

answer

b. zero

explaination:

i wasn't reading it carefully, sorry.

but it is actually 0
