Answer:

La fuerza que realiza el motor es 2035 N.

Explanation:

Podemos encontrar la fuerza del motor usando la siguiente ecuación:

F = ma   (1)

En donde:

m: es la masa del coche = 550 kg

a: es la aceleración

Se puede calcular la aceleración mediante la siguiente ecuación cinemática:

v_{f} = v_{0} + at   (2)

En donde:

v_{f}: es la velocidad final del coche = 100 km/h

v_{0}: es la velocidad inicial del coche = 0

t: es el tiempo = 7,5 s

Resolviendo la ecuación (2) para "a" tenemos:

a = \frac{v_{f} - v_{0}}{t} = \frac{100\frac{km}{h}*\frac{1000 m}{1 km}*\frac{1 h}{3600 s} - 0}{7,5 s} = 3,70 m/s^{2}

Entonces, la fuerza es:

F = ma = 550 kg*3,70 m/s^{2} = 2035 N

Por lo tanto, la fuerza que realiza el motor es 2035 N.

Espero que te sea de utilidad!

A horizontal force of 30N is applied to a mass of 10 kg causing it to accelerate. If the coefficient of friction is 0.20 what is
Blizzard [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

The force of friction is equal to the product of the vertical force applied by the surface to the object in the coefficient of friction.

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

In this question ,

surface vertical force = Weight of the object

Thus ;

svf = ( mass ) × ( gravity acceleration )

_________________________________

If gravity acceleration is 10 :

svf = 10 × 10 = 100 N

So ;

frictional force = 100 × 0.20

frictional force = 20 N

##############################

If gravity acceleration is 9.8 :

svf = 10 × 9.8 = 98 N

So ;

frictional force = 98 × 0.20

frictional force = 19.6 N

dimaraw [331]

Answer:

14 m/s

Explanation:

Using the principle of conservation of energy, the potential energy is converted to kinetic energy, assuming any losses.

Kinetic energy is given by ½mv²

Potential energy is given by mgh

Where m is the mass, v is the velocity, g is acceleration due to gravity and h is the height.

Equating kinetic energy to be equal to potential energy then

½mv²=mgh

V

Making v the subject of the formula

v=√(2gh)

Substituting 9.81 m/s² for g and 10 m for h then

v=√(2*9.81*10)=14.0071410359145 m/s

Rounding off, v is approximately 14 m/s

A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surfac
Y_Kistochka [10]

Answer:

See Explanation

Explanation:

a) We know that;

v = λf

Where;

λ = wavelength of the wave

f = frequency of the wave

v = velocity of the wave

So;

T = 2 * 2.10 s = 4.2 s

Hence f = 1/4.2 s

f = 0.24 Hz

The wavelength =  6.5 m

Hence;

v = 6.5 m * 0.24 Hz

v = 1.56 m/s

b)The amplitude of the wave is;

A =  0.600 m/2 = 0.300 m

c) Since the wave speed does not depend on the amplitude of the wave then the answer in (a) above remains the same

Where d = 0.30 m

A = 0.30 m/2 = 0.15 m
