Answer:

Explanation:
Let:

We need to know for which value of
the function
is equal to
:

Therefore, we need to solve for the previous equation for
:
Replacing the values of
and
:

Subtract 4 from both sides:

Multiply both sides by -1

Divide both sides by 3:

Therefore the value of
for which
is
.
Verify the result:

Answer:
in the nucleus of the atom
Explanation:
a p 3 x
Explanation:
Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium.
The time it takes for a ball to complete the trip is given to be 4.10 s. This implies that the trip going up of the ball is equal to 2.05 s. Using this time to determine the initial speed, we have,
Vf = Vo - gt
Vf is the final speed which is equal to 0 on the topmost location of the ball.
0 = Vo - (9.8 m/s²)(2.05 s)
Vo = 20.09 m/s
At 0.5 s,
Vf = 20.09 m/s - (9.8 m/s²)(0.5 s)
Vf = 15.19 m/s
Thus, the speed of the ball when the height is in level with the top of the flagpole is 15.19 m/s.
