Answer:
False
Explanation:
Its the sum of those not the difference between them
Answer:
The fraction of kinetic energy to the total energy is
.
Explanation:
displacement is one third of the amplitude.
Let the amplitude is A.
x= A/3
The kinetic energy of the body executing SHM is

The total energy is

Divide (1) by (2)

they are miles per hour(mph),kilometers per hour(km/h),meters per second(m/s)
