You want to calculate the displacement of an object thrown over a bridge. using -10 m/s^2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water? show your work!

Answer

The total displacement of the object is 320 m

Solution-

From the formulas of mechanics,

Where,

s = displacement

u = initial velocity = 0               ( ∵ As the body was in rest in the beginning )

t = time taken = 8 s

a = acceleration = -10 m/s²      ( ∵ -ve is because of the downward motion)

Putting all the values,

( ∵ -ve displacement means it is in downwards)

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
