Question

Suppose that an object is dropped from a height of h meters and hits the ground with a velocity of v meters per second. Then y=19.6h. If an object isdropped from a height of 49.5 meters, with what velocity does it hit the ground?Round your answer to the nearest tenth.meters per second5?pt71pt5 A1 ANpt1 AMI Don't KnowSubmit© 2020 McGraw-Hill Education.

Answer 1

We are already told that the velocity with which an object hits the ground is given by

$v=\sqrt[]{19.6h}$

and we are asked to find the velocity when h = 49.5. To do this we just substitute 49.5 for h in the above equation to get

$v=\sqrt[]{19.6\times49.5}$

which evaluates to (the nearest tenth)

$v=31.2$

which is our answer!
