Answer:

For man runs in Olympics with weight is 65kg and Kinetic energy is  1625J, the speed of the man is 7.07m/s

Explanation:

  • Energy of a moving body is known as kinetic energy
  • For a body moving with velocity (V), with mass (m) kinetic energy is given by the formula

       KE=\frac{1}{2}mV^{2}

From the question, we have

weight of the man m=65kg

The kinetic energy of the man KE=1625J

speed of the man  V=\sqrt{\frac{2*KE}{m} }

substitute the values to get the speed of the man

V=\sqrt{\frac{2*1625}{65} } =\sqrt{50} =7.07m/s
