A 10 kg mass is lifted to 3 m. What is its weight? What is its potential energy? How much work is being done?

Respuesta :

Explanation:

weight = mass × gravity force

= 10kg × 10 m/s

= 100 N

potential energy = mass × gravity × height

potential energy = mass × gravity × height = 10 × 10 × 3m

= 300 joules

work = potential energy

= 300 joules
