Answer : The correct answer is 74.83 m/s .
The kinetic energy is energy possessed by any mass which is moving or have some speed . It is product of mass and velocity . It is expressed as : 
 
Where KE = kinetic energy in J or  m = mass in Kg v = speed in m/s²
 m = mass in Kg v = speed in m/s²
Unit of KE is Joules (J) . 
Givne : KE = 2100 J mass = 0.75 kg v = ?
Plugging value in KE formula => 


Dividing both side by 0.375 kg =>
