Non living and dead are the same thing
Given from the problem :mass m = 413 kg;coefficient of friction u = 0.0163;acceleration due to gravity g = 9.8 m/s2;inclined angle @1 = 14.3;inclined angle @2 = 4.69;distance travelled d = 175 m;applied fore F = 410 N; the component of the force from the donkey in the direction of motion isF2 = F1
[email protected]= 397.2964498768165 N
Fy = N - mg
[email protected] = 0N = mg
[email protected] = 4037.964151113007 NFx = F2 - mg
[email protected] - f = mahere f = u N=65.8188156631420141
F2 - mg
[email protected] - f = maa = F2 - mg
[email protected] - f/ m=0.31923412183075155 m/s^2
work done by donkeyW = F2 d=69526.8787284428875 J
As we know that spring force is given as
here we know that
F = 4 N
x = 2 cm = 0.02 m
now from the above equation we will have
so the elastic constant of the spring will be 200 N/m
To solve this problem it is necessary to apply the fluid mechanics equations related to continuity, for which the proportion of the input flow is equal to the output flow, in other words:
We know that the flow rate is equivalent to the velocity of the fluid in its area, that is,
Where
V = Velocity
A = Cross-sectional Area
Our values are given as
Since there is continuity we have now that,
Therefore the speed of the water's house supply line is 0.347m/s
Answer:
Kinetic energy : "It is the energy possessed by body by virtue of its motion" .
Explanation:
The mechanical energy is the energy that a body has due to its motion or position .
It is of two types :
- Potential energy
- Kinetic energy
Potential energy
"It is the energy that a body has due to its position or state" .
It is given by P.E=mgh
Kinetic energy
"It is the energy that a body has due to its motion" .
The formula is : K.E=1/2mv².
For example
- A ball is placed on table .
- At that time it has potential energy .
- Now,lets say that we push it and it drops down .
- On doing this ,the potential energy of ball gets converted into kinetic energy(because it comes in motion ) and as soon as it touches the ground it stops and its kinetic energy gets converted into Potential energy again .
