Given that,

Distance travelled, d = 3.06 m

Final velocity, v = 0.18 m/s

Average velocity of the object, V = 0.34 m/s

To find,

The acceleration of the object.

Solution,

Let t is the time in which it covers distance d. Average velocity is given by distance covered divided by time.

[tex]V=\dfrac{d}{t}\\\\t=\dfrac{d}{V}\\\\t=\dfrac{3.06}{0.34}\\\\t=9\ s[/tex]

Let a is the acceleration of the object. Using equation of motion to find it :

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{0.18-0}{9}\\\\a=0.02\ m/s^2[/tex]

So, the acceleration of the object is 0.02 m/s².

Answer:

Workdone = 147Nm

Explanation:

Given the following data;

Mass = 5kg

Height = 3m

We know that acceleration due to gravity is 9.8m/s²

First of all, we would find the force applied;

[tex] Force = mass * acceleration [/tex]

Force = 5*9.8

Force = 49N

Now, to find the workdone;

[tex] Workdone = force * distance [/tex]

Substituting into the equation, we have;

Workdone = 49 * 3

Workdone = 147Nm

Answer:

46 degrees

Explanation:

90+44+x=180

44+x=90

x=46

Answer:well isn't it 90 like it said on the image?

Explanation?????

Answer:

Force is measured using either the English System of Measurements or the International System of Units A force can cause an object with mass to change its velocity It is measured in the SI unit of newtons and represented by the symbol F.
