Answer:
0.52%
Step-by-step explanation:
t = 5.05 sec
Solution:
Given data:
Initial height = 24 meter
Initial velocity = 22 meter
Height of the rock (h) = 10 meter
To find when will the height of the rock be 10 metres:
General formula for the height(meter) of a projectile over time:
Substitute the given data in the above formula.
This equation looks like a quadratic equation.
We can solve it by using the quadratic formula:
Here a = –4.9, b = 22, c = 14
Time cannot be indicated in negative. So neglect t = –0.56.
Therefore, t = 5.05 sec
Hence after 5.05 sec the rock will be 10 meters from ground level.

Answer:
Yes
Step-by-step explanation:
To see if the Triangle is right use Pythagorean theorem which is A^2+B^2=C^2
A and B are to 10 and 24 because the longest side, the hypotenuse is C
10^2+24^2=676
26^2=676
Therefore the triangle is right
Answer:
This equation demonstrates direct proportionality, as we have the form y=kx where k is the constant of proportionality. Looking at the equation, k=23 is our constant of proportionality because 23 is the constant number we multiply x by.
