The acceleration of the body is 2 m/s^2 while the deceleration is - 1.2 m/s^2.

<h3>What is the acceleration?</h3>

Let us recall that the acceleration is the change in the speed of a body with time. We have been told that the body accelerates for 3s and then decelerates to 2s. This implies that the total time that the object spent in motion is 5 s.

Thus;

v = u + at

v = final velocity

u = initial velocity

a = acceleration

t = time taken

v - u/t = a

a = 6 - 0/3

= 2 m/s^2

Again;

v - u/t = a

a = 0 - 6/5

a = - 1.2m/s^2

<em>1</em><em>.</em><em> </em><em>as </em><em>the </em><em>object </em><em>is </em><em>stationary </em><em>despite </em><em>Jamal </em><em>applying </em><em>100N</em><em> </em><em>forces</em><em>, </em><em>it </em><em>suggests </em><em>that </em><em>the </em><em>object </em><em>i</em><em>s </em><em>applying </em><em>an </em><em>equal </em><em>amount </em><em>of </em><em>force </em><em>on</em><em> </em><em>the </em><em>opposite</em><em> </em><em>direction </em><em>that </em><em>is </em><em>opposing </em><em>the </em><em>force </em><em>applied</em><em> </em><em>by </em><em>Jamal.</em>

<em>2</em><em>.</em><em> </em><em>inertia </em><em>is</em><em> </em><em>a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.</em><em> </em>

You cover the following displacements every day going to school: d1=50 m, E and d2=95 m, N. You do this for 12 minutes. a) What
puteri [66]

The speed will be 0.2 m/s and the velocity will be 0 m/s.

Speed = Total Distance / Total time

We have given total distance as ( 50 + 95 ) metres and total time as 12 minutes or we can say 720 seconds.

Speed = 145/ 720 m/s

Speed = 0.2 m/s

Velocity = Total Displacement / Total time

As the initial and final is the home, hence the net displacement is 0 in that case.

In this case also the total time we have given is 12 minutes or we can say 720 seconds.

Velocity = 0 / 720 m/s

Velocity = 0 m/s

So to conclude with we can say that the speed is 0.2 m/s and the velocity is 0 m/s.

zysi [14]
The ability of solid rock to flow is called Plasticity.

Plasticity is the deformation of a solid mateial which resulted in non reversible changes of shape in response to applied force.

Another example of plasticity is when you bend metal through a forcer force to create an art or kitchen set
