Suppose an object is dropped from a height h0 above the ground. then its height after t seconds is given by h = −16t2 + h0, where h is measured in feet. use this information to solve the problem. if a ball is dropped from 246 ft above the ground, how long does it take to reach ground level? (round your answer to two decimal places.)

It takes 3.92 seconds to reach ground level.

Given that the ball is dropped from 246 ft above the ground.

It means .

If the ball reaches the ground level then h=0.

Using these we solve the equation for t.

The ball will reach the ground in 3.92 seconds.

Step-by-step explanation:

Given:

Height from where ball was dropped

Equation representing the height after t second.

we need to find the time (t) required by ball to reach the ground.

Solution:

To find the value of 't' when , presuming the ground to be at a height of zero.

Substituting the value of in above equation we get;

Dividing both side by 16 we get;

Now taking square root on both side we get;

Rounding to 2 decimal places we get;

t = 3.92 secs

Hence The ball will reach the ground in 3.92 seconds.
