In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.

Cuando una persona sube y baja una escalera, Cuanto vale su desplazamiento y cual es la medida de su trayectoria.
adoni [48]

Answer:

Primero, definimos el desplazamiento como la distancia entre la posición final y la posición inicial.

Así, si comenzamos abajo, luego subimos la escalera, y luego bajamos, la posición final y la posición inicial serán la misma

por lo que el desplazamiento es igual a cero.

La medida recorrida es el espacio total recorrido.

Es decir, si entre el principio y el final de la escalera hay una distancia D.

La persona que sube y baja, recorre esta distancia dos veces.

Entonces cuando una persona sube y baja la escalera, la medida de su trayectoria será 2*D.

An 8 kg block is pushed across a horizontal surface by a horizontally oriented force whose magnitude varies in time. The instant
Naya [18.7K]

Answer:

4.5 m

Explanation:

We are given that

Mass of block,m=8 kg

P_push(t)=(4\frac{W}{s^3})t^3

Apply work energy theorem

Wdt=d(K.E)

Where W=4t^3

Integrating on both sides

\int_{0}^{t} 4t^3dt=\int d(K.E)

K.E=t^4

v=\sqrt{\frac{2K.E}{m}}

v=\sqrt{\frac{2t^4}{8}}=\frac{t^2}{2}

\frac{ds}{dt}=\frac{t^2}{2}

ds=\frac{1}{2}t^2dt

integrating on both sides

s=\int_{0}^{t}\frac{1}{2}t^2 dt

s=\frac{1}{6}t^3

Substitute t=3 s

s=\frac{1}{6}(3)^3=4.5 m

Hence, the displacement of the block after 3 s=4.5 m

The Pilot of a plane measures an air velocity of 165Km/h south relative to the plane. An observer on
AVprozaik [17]

The speed obtained by the pilot is not accurate since it is measuring the rate of travel in the wind, true velocity is that compared to the ground. Therefore the speed of the wind is:

v wind = 165 - 145

v wind = 20 km/h<span>

<span>Therefore the wind velocity = 20 km/h against the plane.</span></span>

A 10-KG cart moving at 5 m/s collides with a 5 KG cart at rest and causes it to move 10 m/s. Which principal explains the result
IgorLugansk [536]

Answer: energy transfer. or, kinetic energy.

Explanation:

when something collides with another, it transfers kinetic energy to the other it collided with, making it move.
