Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

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?

Answer 1

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

Step-by-step explanation:

We have equation of motion ,
`s= ut+(1)/(2) at^2`, 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
`m/s^2`, we need to calculate displacement when time = 8 seconds.

`s= 0*8+(1)/(2) *10*8^2\\ \\ s=320m`

So displacement of object = 320 meter
