kinetic energy of man ka kya tha
ya @ ankur rite
K.E. i got 20000-50000 J
ankur dats height nd distances rite
nd ke also i gt 2000-5000
ya for screw it is 3.38
its 3.73 man
speed = v = at......v=20m/s
ke= 1/2 *400*mass.
200*mass. mass of athlete must be 50-100kg
it is then 1000-20000 and we dont know that if he attained a higher speed and then slowed down.............so choosen that one.....is it correct?
i got 3.73..?? :(
well wat abt speed of sound measuring???is it 54<x<18??
The question of height and distance..if the person is moving along BC,that means he is moving away from the pole..so the angle with the pole should increase..but its given that its decreasing...isnt the question wrong??
