Question

3. If 2 J of wok is done in raising a 180 g apple, how far is it lifted?

Answer 1

1.13m

Step-by-step explanation:

From the question, we obtained the following information:

W = 2J

m = 180g

We must convert this gram (i.e 180g) to kg

1000g = 1Kg

180g = 180/1000 = 0.18kg

g = 9.8m/s2

h =?

w = mgh

h = w / mg

h = 2 / ( 0.18x9.8)

h = 1.13m
