An object travels at 3.06 m distance with uniform acceleration in this interval it's velocity increases by 0.18 and it's average velocity over the interval was 0.34 m/s what is the acceleration?
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.
A 5 kilogram block is dropped from a height of 3 meters and falls straight to the ground. What is the work done by the force of gravity?
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
