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

The objects do not reach terminal velocity there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
