a 4.5 kg textbook is sitting on a table 0.8 meters above the ground. how much gravitational potential energy does the textbook have? remember : $e_g = mgh$ $g = 10 \\frac{m}{s^2}$ $e_g = ? j$

a 4.5 kg textbook is sitting on a table 0.8 meters above the ground. how much gravitational potential energy does the textbook have? remember : $e_g = mgh$ $g = 10 \\frac{m}{s^2}$ $e_g = ? j$

Answer

Explanation:

Step1: Identify the values

We have ( m = 4.5\space kg ), ( g = 10\space \frac{m}{s^2} ), and ( h = 0.8\space m ). The formula for gravitational potential energy is ( E_g = mgh ).

Step2: Substitute the values into the formula

Substitute ( m = 4.5 ), ( g = 10 ), and ( h = 0.8 ) into ( E_g = mgh ). So we get ( E_g = 4.5\times10\times0.8 ).

Step3: Calculate the result

First, calculate ( 4.5\times10 = 45 ), then ( 45\times0.8 = 36 ).

Answer:

36
