Answer:
a) 2.85 m/s
b) -24.01 m/s
c) 1
Explanation:
From the question, we can attest that the motion of the fish that was dropped by the seagul is that of a projectile motion. This motion is made up of two other motions which are, a horizontal uniform motion and a vertical motion, at constant acceleration. From the question, we are asked to find the horizontal motion. And then, the horizontal component of the fish's velocity does not change, therefore its the horizontal component of the fish's velocity is 2.85 m/s
To find the vertical component of the fish's velocity, we use the equation
v(y) = u(y) + gt
Where u(y) is the initial velocity which is zero, and g is the acceleration due to gravity which is -9.8 m/s. We are also told from the question that it took 2.45 s, and that's our time t. Applying this into the equation, we have
v(y) = 0 + -9.8 * 2.45
v(y) = -24.01 m/s
For the 3rd part, the horizontal component of the fish's velocity would decrease
Answer:
A .endoplasmic reticulum
Explanation:
Endoplasmic reticulum is the part of the plant cell that is responsible for the synthesis of proteins.
I know from experience that if you put plants in the hill,trees, bushes, flowers and whatnot. Most erosion and landslides are caused by water that has soaked through the soil causing it to become soft. But the plants soak up the water through the roots, making it harder to flood (Which means the ground has soaked up to much water so it floods)
Answer:
<h2>50 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>50 J</h3>
Hope this helps you
I don't know what " hm/h " means as a unit of speed. But if the bright red object is traveling in a straight line at a constant speed, then its acceleration is zero, and that means that the net force acting on it is zero. The same would be true of a car of any other color traveling with the same velocity.
