Infer whether a system can have kinetic energy and potential energy at the same time
trapecia [35]
A system can have kinetic and potential energy, for example, an object falling but it hasn't reached the ground. It's still in the air, and has "potential" to go faster or hit something on it's way down, but since it's moving it also has kinetic energy.

A cargo elevator on Earth (where g = 10 m/s2) lifts 3000 kg upwards by 20 m. 720 kJ of electrical energy is used up in the proce
MakcuM [25]

Answer: 83%

Explanation:

Efficiency of the process = work output/work input × 100%

Work input is the energy used up in the process = 720,000Joules

Work output = Force × distance

= (3000×10)× 20

= 600000 Joules

Efficiency= 600000/720000 × 100

= 0.83×100

= 83%
