Question

calculate the energy passed by store of mass 10gram at height of 5 metre?​

Answer 1

Answer:

use this as model

Explanation:

for Example

Calculate the energy transferred to the gravity store when a woman of mass 60 kg climbs 4 rungs up a ladder. Each rung is 15 cm high.

First calculate the distance climbed in metres:

15 cm is 0.15 m

0.15 × 4 = 0.6 m

Then calculate the gravity store increase (the gravitational potential energy), remembering that g is 10 N/kg on Earth:

gravitational potential energy = mass × height × gravitational field strength (g)

gravitational potential energy = 60 × 0.6 × 10

gravitational potential energy = 360 J
