An increase in a sound's pitch corresponds to an increase in the frequency!
Jemima is running with a velocity of 5m/s. She has a mass of 65kg, what is her kinetic energy would be 812.5 Joules.
<h3>What is mechanical energy?</h3>
Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.
As given in the problem we have to calculate the Kinetic energy of the Jemima,
Kinetic energy = 1/2 ×mass×velocity²
=0.5×65×5²
=812.5 Joules
Thus, the kinetic energy of the Jemima would be 812.5 Joules.
