If the speed is doubled then the kinetic energy will be 3000J.
Explanation:
The kinetic energy is calculated by ,
KE =(1/2) (M x V x V)
750 = (1/2) (M x V x V)
750(2) = M x V x V
1500 = M x V x V
If the speed is doubled then the kinetic energy will be
KE = (1/2) ( M x 2V x 2V)
KE = (1/2) (4) (M x V x V)
The value of (M x V x V) = 1500
So,
KE = (1/2) (4) (1500)
KE = 3000J
If the speed is doubled then the Kinetic energy will be 3000J
