A particle starts from the origin at t = 0 with an initial velocity of 5.3 m/s along the positive x axis.If the acceleration is
Aleks04 [339]

Answer:

Velocity at the point of maximum x cordinate is 9.578m/s

Position vector of the particle when it reaches point of maximum x ordinate is \overrightarrow{r}=5.402\widehat{i}+9.76\widehat{j}

Explanation:

We shall resolve the motion of the particle along x and y direction separately

The particle will reach it's maximum x coordinate when it's velocity along x axis shall become 0

We have acceleration along x-axis = -2.6m/s^{2}

acceleration along y-axis = 4.7m/s^{2}

Thus using the first equation of motion along x axis we get

v_{x}=u_{x}+a_{x}t\\\\

Applying values we get

0=5.3-2.6t\\\\\therefore t=\frac{5.3}{2.6}sec\\\\t=2.038sec

Now to obtain it's position we shall use third equation of motion

v_{x}^{2}=u_{x}^{2}+2as_{x}\\\\0=(5.3)^{2}+2(-2.6)s_{x}\\\\\therefore s_{x}=\frac{-28.09}{-5.2}m\\\\s_{x}=5.402m

Now it's location along y- axis can be obtained using 2nd equation of motion along the y axis

s_{y}=u_{y}t+\frac{1}{2}a_{y}t^{2}

Applying values as follows we get

u_{y}=0\\a_{y}=4.7m/s^{2}\\t=2.038s

s_{y}=0\times 2.038+\frac{1}{2}\times 4.7m/s^{2}\times2.038^{2}\\\\s_{y}=9.76m

thus the position vector of the particle when it reaches it's maximum x co-ordinate is

\overrightarrow{r}=5.402\widehat{i}+9.76\widehat{j}

Now velocity of the particle at the position of maximum x co-ordinate shall be zero along x-axis and along the y-axis it can be found along the first equation of motion along y axis

v_{y}=u_{y}+a_{y}t\\\\v_{y}=0+4.7\times 2.038\\\\v_{y}=9.578m/s

Answer:

the answer is the explaination

Explanation:

Present beach erosion prevention methods include sand dunes, vegetation, seawalls, sandbags, and sand fences. Based on the research conducted, it is evident that new ways to prevent erosion must be obtained. Each way that is currently used has extensive negative effects on beaches and their natural tendencies.

What can engineers do to prevent structures from collapsing during earthquakes
vredina [299]

Explanation:

1. The structures should be made with good quality steel and concrete so that they can bear load and deformation.

2. Buildings should be made laterally strong so that they can overcome dominant lateral forces.

3. In High seismic activity areas devices such as energy absorbers should be used. Base isolation must necessarily be done.

4. Use of hybrid Fiber Reinforced Concrete to increase the toughness of a structure in a Moment Resisting Frame. Moment resisting frames are frames that resist moment of any devices.
