What is the thigh length in cm? 21.5, 56 cm What is the angle of the thigh in relation to the Right Horizontal?

Explanation / Answer

Here we have given table of time and position.

Now we have to find average speed of this data.

The formula for average speed is,

Vav = total distance travelled / total time required for the travel

Vav = 5.21 / 0.05 = 104.2m/s

Now we have to find instantaneous velocity.

And the formula is,

Instantaneous velocity = x2 - x1 / t2 - t1

where x1 is initial position

x2 is final position

t1 is initial time and

t2 is final time

Instantaneous velocity at frame 2 :

Here x1 = 1.034 x2 = 1.041 t1 = 0.000 and t2 = 0.005

Instantaneous velocity = 1.041 - 1.034 / 0.005 - 0.000

= 0.007 / 0.005 = 1.4 m/s

Now instantaneous velocity at frame 5 :

x1 = 1.041 x2 = 1.044 t1 = 0.015 and t2 = 0.02

Instantaneous velocity = 1.044 - 1.041 / 0.02 - 0.015

= 0.003 / 0.005

= 0.6 m/s
