Answer:
- Corey's max speed is
- the distance Corey's covers in z seconds is
Explanation:
<h3>Corey's max speed</h3>
For constant speed, we know:
The distance between the 80 meters and the 45 meters is:
and the time it took to reach the 80 meter will be:
So, Corey's max speed is
<h3>
How far runs Corey</h3>
As the velocity of Corey's is 
, the distance Corey's covers in z seconds is
<h3>What is Corey's distance from the starting line</h3>
At time 7 + z seconds the distance will be the 45 meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:
At time x ( x greater or equal to 7 seconds) the distance will be the 45 meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:
B force i belive becuase when is done it force

200 gm/40 cc
= 5 gm/cc
Answer:
<em>a. The rock takes 2.02 seconds to hit the ground</em>
<em>b. The rock lands at 20,2 m from the base of the cliff</em>
Explanation:
Horizontal motion occurs when an object is thrown horizontally with an initial speed v from a height h above the ground. When it happens, the object moves through a curved path determined by gravity until it hits the ground.
The time taken by the object to hit the ground is calculated by:
The range is defined as the maximum horizontal distance traveled by the object and it can be calculated as follows:
The man is standing on the edge of the h=20 m cliff and throws a rock with a horizontal speed of v=10 m/s.
a,
The time taken by the rock to reach the ground is:
t = 2.02 s
The rock takes 2.02 seconds to hit the ground
b.
The range is calculated now:
d = 20.2 m
The rock lands at 20,2 m from the base of the cliff
