Arock is thrown upward with the velocity of 27 meters per second from the top of a 43 meter high cliff, and it misses the cliff on the way back down. when will the rock be 8 meters from ground level?

The rock will be 8 meters from ground level in 6.6 seconds.

Solution:

The value of gravity,

To find: The time when h(t) = 8 m from ground level

Using quadratic formula:

Here, the unknown value x is considered as t. On substituting the values of a as -4.9; b as 27 and c as 35 we get,

Square root of 1415 is 37.61648 which is approximately 37.6

On ignoring the negative value since time will be of positive value we get,

b.my answer is b.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
