Question

If 2 J of wok is done in raising a 180 g red delicious apple to bring it to your mouth to take a bite of the apple, how far is it lifted?

Answer 1

Answer:1.13m

Step-by-step explanation:

Potential Energy= mgh

m= mass(kg)

g= gravitational field strength(9.81m/s^2)

h= height

PE=mgh

PE= 2J

therefore: 2J= 0.180kg x 9.81 m/s^2 x h

h= 2/(1.764)

h= 1.13m
