Question

A 1.5 kg water bottle with potential energy of 17.9j. What is the height of the water bottle from ice surface

Answer 1

Solution:

$$E=m\times g \times H$$

$m=1.5 kg$

$E=17.9 j$

$g=9.8 \frac {m}{s^2}$

$$H=\frac {E}{mg}$$

$$H=\frac {17.9}{1.5\times 9.8}$$

$$H=1.22 m$$

Answer: 1.22 m
