Explain how energy derive from meat got into meat. Calculate the kinetic energy of arrow mass 0.9kg moving with a velocity of 15m/s.

Answer»

ong>EXPLANATION:

  • Given : M = 0.9 kg
  • V = 15m/s
  • To find : K.E

  • We know that
  • K.E = 1/2mv²
  • K.E = 1/2×0.9×15²
  • K.E = 0.45 × 225 ( Divide 0.9 by 2)
  • K.E = 101.25 J
