Un corp coboară liber pe un plan înclinat cu unghiul °≅37α față de orizontală()6,0sin=α. Coeficientul de frecare la alunecare între corp și suprafața planului este .5,0=μ Accelerația corpului este?

answer; (arch); good luck

false

explanation:

boats, things on boats luggage are way more heavy then water.

i think the answer is a, hope this is right, that would be my best guess.

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                                         : )
