Suppose wave pulses in an aquarium are produced by a mechanical motor that moves a bob up and down at the surface. the setup uses a 10-w motor and has a period of 1.9 s between bobs. how much kinetic energy is in each pulse.

kinetic energy in each pulse = 9.5J

Explanation:

Conventionally, overall energy = kinetic + potential

Hence kinetic energy in each pulse = half of the total energy = 0.5 x 19

energy = 9.5J
