Question

41. Two athletes cover a distance of 100 m in 9.854
seconds and 9.841 seconds. Find the difference
between the place value of the digit 4 in both the
numbers.​

Answer 1

Answer:

As we discussed in 

Kinetic energy -

- wherein

kinetic Energy is never negative

 

  



Initial velocity = 0 

Final velocity vf.

    

    a = 2 m/s2

Maximum speed = at = 20 m/s2

Maximum K.E.    (Assume m = 50 kg)

    

If it run with constant velocity v = 10 m/s

Then K.E.

So it lies between 2500 to 10,000 J.
