726 inches per 0.31 seconds is: 726/0.31 (in/s)\n\n==> 2341.9 (in/s) = 133.0 miles/hr\n\nHope that helps.\n\n:)

‘impulse’ or momentum\n=m*(v2-v1)=0.42*(-17-4.1)=-8.862 kg*m/s

In physics,\n\nEnergy is always measured in Joules.\n\nMass is always measured in Kilograms.\n\nSpeed or Velocity is always measured in Meters per Second.\n\nthose are the SI units.

Ek = 1/2.m.v2   (1/2 mass times velocity squared) - \n\nsorry can't do superscript on this site

Try this:\nHigh velocity causes increase in mass and high expenditure of energy.

questions are very easy. You must try them by yourself. I will only give hints-\n1> Instantaneous accl  = dv/dt\nAvg accl = (v2-v1)/(t2-t1)\n\n2> draw the vectors, take the components separately along x and y axes.\nremember accl component along x axis increases velocity along x axis, and accl component along y axis increases velocity along y axis.\n3> use the basic kinematics equations like v^2=u^2+2as etc

Nerve impulse is connected with Na and K while muscle contraction has to do with Ca and Mg

For a back row spike I found 26.7-27.6m/s (mean).  Sorry, but that was all I could find!  I was going to do a study on it - but then I switched out of biomechanics into exercise physiology.  You could do it by calculating time elapsed between contacting the ball and the ball reaching the floor.  You would have to know the height at which the ball was contacted and how far it traveled horizontally from the point of contact.  They you find the hypotenuse using Pythagorean theorem and divide this number by the time to get an estimated velocity.

The higher the EMG signal, the more action potentials there are innervating the muscle.  The stronger the contraction of the muscle, the more motor units are being used, so there are more AP's.  Thus the strong the contraction, the higher the EMG signal.  I believe it would be a linear relationship.
