Question

Derive the equation of motion by graphical method

Answer 1

Answer:

Explanation:

Velocity-Time Relation

A car having initial velocity u , is being subjected to a uniform acceleration a for a time period of t , after the time t the final velocity of the car is v.

Now we need to find the relation between v,u,a,t graphically.

Position-Time Relation

A car having initial velocity u , is being subjected to a uniform acceleration a for a time period of t , after the time t the final velocity of the car is v.

In the time interval of time t , it covers a distance of s.

Now we need to derive relation between s,u,a,t graphically.

Answer 2

Explanation:

To calculate the standard deviation for a sample of N measurements:

Sum all the measurements and divide by N to get the average, or mean.

Now, subtract this average from each of the N measurements to obtain N "deviations".

Square each of these N deviations and add them all up.

Divide this result by. (N − 1)
