yes but can you please explain it...

viscous force and velocity

im sorry but i dont understand this...

ok, yeah i get it but then can you pls explain why they both are directly proportional?

no but i was asking i do know the answer i D but can you explain how the graph relates to an object moving up in a projectile...

so then why does viscous force increases as speed increases?

the correct horizontal displacement with time would be a straight line passing from origin

is it wrong?

my answer was D, which is correct considering the motion downwards eg, object thrown from a cliff but what if an object is moving up?like a football being kicked? i cant understand how this graph applies to that...

my answer was A but i dont understand because when the viscous force equals the weight speed becomes constant but why does the viscous force needs to be equal of weight? is it weight = viscous force? or speed = viscous force?

done

w= is by box on earth b= by earth on box so...?

my answer = F = 1.6*9.81 - 1.2*9.81 = 3.924 N -> resultant force of the drone moving (weight minus the upward force) M= 1.2kg , mass of drone a= 3.31 m/s^2 , acceleration of drone u=0 m/s , initial speed of drone t=1s , time v = 3.27 m/s, final speed of drone and its not even in the options... 😶

my answer was B because wont it B be as its the normal reaction force? due to the newtons 3rd law?? correct answer is A...

a) equilibrium b) inside base c) outside base the green pic, tip of base another question for green pic would the block return back or fall over??
