A hydraulic lift lifts a 1,150 kg car at the rate of 3 cm per second. calculate:
a) the power of the elevator.
b) the work done in one minute.
Sol.:
a) 338.1 Watts
b) 20286 Joules​

answer: strength i guess

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
