b)The skateboarder need to barely clear the pool 9.77 m/s.

The speed at which an object's location changes in any dimension. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Given that it just has a path and no amount, speed is still a scalar number.

a)Width of the pool, d= 10 m

Height of the building, h = 12 m

h = v₀t + 1/2 gt²

h = 0 + 1/2 gt²

gt² = 2h

t = √2h/g

t = √ 2 * 12 / 9.8

t = 2.56s

b)The skateboarder's required beginning speed to clear the pool is calculated as follows:

In shallow water, waves frequently bend and start to run parallel to the shore. Refraction is the word for this procedure.

Refraction, which also happens with sound, movement, and other waves, is the bending if light as it passes through transparent materials. Because of this bending brought on by refraction, we are able to make lenses, magnifying glasses, dichroic, and rainbows.

When light strikes a medium on a plane, reflecting is the act of the light reflecting back. Refraction seems to be the process by which a material changes the route that light takes as it passes through it, allowing the light to bend.

The force (magnitude and direction) exerted on her by the bungee cord at an instant when her downward acceleration has a magnitude of 5.2 m/s2 is 230.4 N .

The resultant force (F) for Newton's second law is equal to the mass (m) multiplied by the acceleration (a). There are two forces at work: the weight and the force of the bungee cord (Fb). They are moving in the same direction but in opposite directions, hence the resulting force will be their differences

M*g - Fb = M*a

As a result of the downward acceleration, it is -5.2 m/s2.

Fb - 48*10 = 48*(-5.2) (-5.2)

Force and acceleration are directly correlated, as demonstrated by Newton's second law of motion. An object of a given mass will accelerate more quickly the more force is applied to it. For instance, when the force acting on an item is doubled, so is the acceleration.

The final velocity of the rocket is Vf = Vi < 5/4, -1/2 >. Hence, Option E is the correct answer.

We have a mass of the rocket = m

The velocity of the rocket = vi  

The rocket is traveling in the x-direction and the fuel is ejected in the y-direction.

mass of the fuel= m/5

the speed at which the fuel is ejected= 2vi

Now, let us find the final velocity along the x-direction i.e. vx

[tex]m_{rocket}[/tex] * vi = [tex](m_{rocket} -m_{fuel})[/tex] * vx

m*vi = (m-m/5)vx

m*vi = (4/5)m*vx

hence, we have vx = (5/4) vi

Similarly, along the y- direction,

0 = [tex]m_{fuel}[/tex] * 2vi + [tex](m_{rocket} -m_{fuel})[/tex]vy

0 = m/5 * 2vi + (m-m/5)vy

0 = m/5 * 2vi + (4/5)m * vy

(4/5)m * vy = - m/5 * 2vi

(4/5)m * vy = - m/5 * 2vi

vy = -(1/2)vi

What is kinetic energy?
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the object, which then moves at a new, constant speed. Kinetic energy is the type of energy that is transferred and is dependent on the mass as well as speed attained. Kinetic energy can be converted into different types of energy and transferred between objects. A flying squirrel may run into a chipmunk that is standing still, for instance. Some of the squirrel's initial kinetic energy may have been transferred to the chipmunk or changed into another form of energy after the collision.
