Your younger brother gets a new toy car as a present. He winds up the toy, puts it on the ground and watches it accelerate for 5 seconds. You can explain how to find the net force acting on the toy car for the 5 seconds while accelerating by the following:

a
Use a meterstick and stopwatch to measure the distance the car travels for the 5s.
b
Use a balance to determine the mass of the car. Use a motion sensor to measure the speed of the car at a time of 0s and at time of 5s .
c

Answers

Answer:

b  Use a balance to determine the mass of the car. Use a motion sensor to measure the speed of the car at a time of 0s and at time of 5s .

Explanation:

The right way to measure the net force on the car is take the measurement of its mass then find the speed of the car within the time 0s to 5s.

This is because the net force acting on car is given as;

   Force  = mass x acceleration

By using the balance, the mass is determine

 Acceleration is the rate of change of velocity with time.

     Acceleration  = [tex]\frac{v - u}{t}[/tex]  

v is the final velocity

u is the initial velocity

t is the time taken

  Now,

         Force  = mass x  [tex]\frac{v - u}{t}[/tex]

How much does a 20 kg rock weigh on Earth where g = 9.8 m/s2?

Answers

Answer:

[tex]\huge\boxed{196\:N}[/tex]

Explanation:

Mass and weight ain't the same thing. So, for calculating weight we would use Newton's 2nd Law of Motion i.e. Force = Mass × Acceleration.

According to question,

The mass is 20kg

Acceleration is 9.8 m/s^2

Putting the given values into the formula,

F = 20 × 9.8

F = 196N

So, the weight of the rock is 196 N

A gun fires a bullet horizontally with a velocity of 90 m/s from a tower. Neglecting air resistance, how far will the bullet travel horizontally in 4 seconds?​

Answers

Answer:

The distance covered along the horizontal axis is [tex]s = 360 \ m[/tex]

The distance covered along the vertical  axis is  [tex]h = 78.4 \ m[/tex]

Explanation:

From the question we are told that  

    The horizontal velocity is  [tex]u_x = 90 \ m/s[/tex]

     The time considered is  [tex]t = 4 \ s[/tex]

Generally the distance which the bullet will cover in the horizontal direction for the given time is  mathematically represented as

    [tex]s = u_xt + \frac{1}{2}* at^2[/tex]

Here a is the acceleration along the horizontal direction and the value is  [tex]a = 0 \ m/s^2[/tex]

So

     [tex]s = 90 * 4 + \frac{1}{2}* * 0 * 4^2[/tex]

=>  [tex]s = 360 \ m[/tex]

Generally the distance which the bullet will cover in the vertical  direction for the given time is  mathematically represented as

            [tex]h= u_y t + \frac{1}{2}* gt^2[/tex]

Here  [tex]u_y[/tex] is the initial  velocity of the bullet along the vertical axis and the value is  [tex]u_y = 0 \ m/s[/tex]

             [tex]h = 0 * 4 + \frac{1}{2}* 9.8 *4^2[/tex]

=>          [tex]h = 78.4 \ m[/tex]

What are mechanical waves and electromagnetic waves?

       Usually, waves transfer energy from one place to another. Mechanical waves transfers via matter where as electromagnetic waves transfers via light. Both mechanical waves and electromagnet (light) waves measured through amplitude, wavelength, frequency and both will get transmitted, refracted, reflected, absorbed, diffracted when they react with matter. Both the electromagnetic waves and mechanical waves are transverse in nature but the mechanical waves can also be in longitudinal.

So, many characteristics were similar for mechanical waves and electromagnetic waves.

Hence, Option A, B, C are the three characteristics.

A pulse with a height of 20 cm and a length of 30 cm travels with a speed of 400 cm/s through a spring that has been stretched so it is 800 cm long. If we want to send another pulse through the spring that will have a different speed, which of the bolded words should we change? List all that will change the speed of the wave.

Answers

Answer:

To send a pulse of different speed, change the tension or stretch on the spring

Explanation:

A pulse is a single disturbance of a particle is a medium. The pulse has an amplitude or and a pulse length in the medium. The speed of the pulse is dependent on the amount of strain or tension ( stretch) applied to the medium. The speed also determines the length of the pulse but is unaffected by the or amplitude of the pulse.

Thor deja caer su martillo de la torre Torre Stark que tiene 95 pisos, si al llegar el Mjolnir al piso han transcurrido 9.5 segundos. Determina: a) La velocidad con la que el Mjonir golpea el suelo

Answers

Answer:

La magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.

Explanation:

Podemos encontrar la velocidad con la que el martillo golpea el suelo usando la siguiente ecuación:

[tex] v_{f} = v_{0} - gt [/tex]   (1)

En donde:

[tex] v_{f}[/tex]: es la velocidad final =?

[tex] v_{0}[/tex]: es la velocidad inicial = 0 (lo deja caer)

g: es la gravedad = 9.81 m/s²

t: es el tiempo = 9.5 s

Al reemplazar los valores anteriores en la ecuación (1), tenemos:

[tex] v_{f} = 0 - 9.81 m/s^{2}*9.5 s = -93.2 m/s [/tex]                

El signo negativo se debe a que el vector velocidad está dirigido hacia abajo en el eje vertical (y).

Por lo tanto, la magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.

оа

Oc
Od
48.3 m/s
-68.4 m/s
84.7 m/s
-57.6 m/s

Answers

Answer:

a= g = - 9.81 m/s2.

The following equations will be helpful:

a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad

When you substitute the specific acceleration due to gravity (g), the equations are as follows:

g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd

If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:

g = vf /t d = 1/2 gt2 vf2 = 2gd

The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.

You are trying to climb a castle wall so, from the ground, you throw a hook with a rope attached to it at 24.1 m/s at an angle of 65.0° above the horizontal. If it hits the top of the wall at a speed of 16.3 m/s, how high is the wall?

Answers

Answer:

The value is  [tex]h = 13.2 \ m[/tex]

Explanation:

From the question we are told that

    The speed of the rope with hook is [tex]u = 24 .1 \ m/s[/tex]

     The angle is  [tex]\theta = 65.0^o[/tex]

      The speed at which it hits top of the wall is  [tex]v = 16.3 m/s[/tex]

Generally from kinematic equation we have that

      [tex]v_y^2 = u_y ^2 + * 2 (-g)* h[/tex]

Here h is the height of the wall so

      [tex][16.3 sin (65)]^2 = [24.1 sin (65)] ^2+ 2 (-9.8)* h[/tex]

=>    [tex]h = 13.2 \ m[/tex]
