Answer:

Explanation:

Please try to take a better photo as it is difficult to read.

For the first case, it is a small force to the right as there is a small velocity change.

For the second case, there is no force as there is no change in velocity

For the third case, it is a large (could be medium but photo is too blurry) force to the right as there is a large change in velocity.

In damped harmonic oscillation, the amplitude of oscillation becomes one third after 2 second. If A0 is initial amplitude of osc
Harman [31]

Answer:

A=\frac{A_0}{\sqrt 3}

Explanation:

Initial amplitude=A_0

We are given that

Amplitude after 2 s=A=\frac{1}{3}A_0

We have to find the amplitude after 1 s.

We know that amplitude at any time t

A=A_0e^{-\alpha t}

Using the formula

\frac{A_0}{3}=A_0e^{-2\alpha}

\frac{1}{3}=e^{-2\alpha}

3=e^{2\alpha}

ln 3=2\alpha

\alpha =\frac{ln 3}{2}=ln\sqrt 3

e^{\alpha}=\sqrt 3}

When t=1 s

A=A_0e^{-\alpha}=\frac{A_0}{\sqrt 3}

I think these two are simple questions.. but I need help asap..... TT

1) The average velocity is 56 m/min

2) The average velocity is -83 m/min

Explanation:

1)

The average velocity of an object is given by

v=\frac{d}{t}

where

d is the displacement (change in position)

t is the time elapsed

In the graph in the problem, the displacement corresponds to the distance, therefore to the change in the y-variable (\Delta y), while the time elapsed is the change in the x-variable (\Delta x), so the average velocity can be written as

v=\frac{\Delta y}{\Delta x}

At point A, we have:

y_A = 5 m\\x_A = 0.1 min

At point B, we have:

y_E = 55 m\\x_A = 1 min

So, we have

\Delta y= 55 -5 = 50 m\\\Delta x = 1.0-0.1 = 0.9 min

So the average velocity is

v=\frac{50 m}{0.9 min}=56 m/min

2)

In this part instead, we have the following:

At point F, we have:

y_F = 55 m\\x_A = 1.3 min

At point H, we have:

y_H = 30 m\\x_A = 1.6 min

So, we have

\Delta y= 30 -55 = -25 m\\\Delta x = 1.6-1.3 = 0.3 min

So the average velocity is

v=\frac{-25 m}{0.3 min}=-83 m/min
