If the velocity of a car is 45km/h west, how far can it travel in 0.5 hours
Answer:
22.5km
Explanation:
Since 0.5 of an hour is half of an hour, you have to divide 45 by half, and you would get 22.5 km

What are some of the skills required to play floor hockey?
Answer:
Skills required to play floor hockey include passing, receiving passes, shooting, stick- handling (dribbling), defensive skills and goaltending. Players are allowed to use both sides of the blade of the stick. The front side is called the forehand (face) and the back side is called the backhand.
Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es: *
Answer:
B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.
Explanation:
Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es
A. Cinética, debido a que existen trenes elevados los cuales poseen altura y la altura está asociada con la energía cinética.
B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.
C. Rápida, porque la energía cinética es sinónimo de rápido.
D. Potencial, debido a la potencia que tiene el tren para moverse.
Solution:
La energía cinética es la energía contenida en un objeto en movimiento. La energía cinética se puede definir como la cantidad de energía necesaria para que un objeto se acelere desde el reposo hasta su velocidad final.
La energía cinética (KE) viene dada por:
KE = (1/2) * masa * velocidad²
Podemos ver que la energía cinética depende de la masa del objeto y la velocidad del objeto.
El tren de alta velocidad posee energía cinética debido a la velocidad del tren.

Define 1 pascal pressure
Answer:
Hey mate....
Explanation:
This is ur answer.....
A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. For example, standard atmospheric pressure (or 1 atm) is defined as 101.325 kPa. The millibar, a unit of air pressure often used in meteorology, is equal to 100 Pa.
Hope it helps you,
mark me brainliest plz.....

pascal is the SI unit of pressure symbolized by Pa
1 Pa=1N/m^2
1Pa=1kg/ms^2

Where is the most and the least KENETIC ENERGY
Answer:
Where is kinetic energy the least?, and most?
Explanation:
Least : When the Moon is farthest from Earth in its nearly elliptical orbit, its speed is least. Its kinetic energy has become least, and its potential energy is greatest.
Further : Kinetic energy, form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.
May be different for you, but i really hope I helped out.

What is the velocity of an 80 kg person skating across the ice with a kinetic energy of 16, 000 joules?
Answer:
V = 20 m/s
Explanation:
Given the following data;
Mass = 80kg
Kinetic energy = 16,000 joules
To find the velocity;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the formula, we have;
16000 = ½*80*V²
16000 = 40V²
V² = 16000/40
V² = 400
Taking the square root of both sides, we have;
V = 20 m/s

Una bola se lanza verticlamente de la parte superior de un edificio con una velocidad inicial 25 m/s la bola impacta al suelo en la base del edificio 7 segundos despues de ser lanzada ¿que altura subio la bola
Answer:
S = 415.1 meters
Explanation:
Dados los siguientes datos;
Velocidad inicial = 25 m/s
Tiempo, t = 7 segundos
Para encontrar la altura (desplazamiento) de la pelota, usaríamos la segunda ecuación de movimiento;
[tex] S = ut + \frac {1}{2}at^{2}[/tex]
Dónde;
S representa el desplazamiento o altura medida en metros.
u representa la velocidad inicial medida en metros por segundo.
t representa el tiempo medido en segundos.
a representa la aceleración medida en metros por segundo cuadrado.
Sustituyendo en la ecuación, tenemos;
[tex] S = 25*7 + \frac {1}{2}*(9.8)*7^{2}[/tex]
[tex] S = 175 + 4.9*49 [/tex]
[tex] S = 175 + 240.1 [/tex]
S = 415.1 meters
How much power is needed to lift a 20-kg object to a height of 4.0 m in 2.5 seconds?
Answer:
313.92w
Explanation:
Formula for power:
P=W/∆t = Fv
Givens:
m=20kg
∆y=4.0m
∆t=2.5s
a=9.81m/s²
In order to find power, we first need to solve for work.
W=Fd (force*displacement), f=mg
W=mg∆y
W=(20kg)(9.81m/s²)(4.0m)
W=784.8J
P=W/∆t
P=784.8J/2.5s
P=313.92 watts
