Correct answer only ! 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!

  Displacement of object before hitting water surface after 8 seconds = 320 meter

Explanation:

We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

In this case initial velocity = 0 m/s, acceleration = 10 , we need to calculate displacement when time = 8 seconds.

So displacement of object = 320 meter

whichever one it is, it's definitely not one that you included on the list you provided.
