a 1.4 kg wall clock is hanging 2.7 meters above the ground. how much gravitational potential energy does the wall clock have? remember : $e_g = mgh$ $g = 10 \\frac{m}{s^2}$ $e_g = ? j$

a 1.4 kg wall clock is hanging 2.7 meters above the ground. how much gravitational potential energy does the wall clock have? remember : $e_g = mgh$ $g = 10 \\frac{m}{s^2}$ $e_g = ? j$

Answer

Explanation:

Step1: Identify the values

We have ( m = 1.4 , \text{kg} ), ( g = 10 , \frac{\text{m}}{\text{s}^2} ), and ( h = 2.7 , \text{m} ). The formula for gravitational potential energy is ( E_g = mgh ).

Step2: Substitute the values into the formula

Substitute ( m = 1.4 ), ( g = 10 ), and ( h = 2.7 ) into ( E_g = mgh ). So we get ( E_g = 1.4 \times 10 \times 2.7 ).

Step3: Calculate the result

First, calculate ( 1.4 \times 10 = 14 ), then calculate ( 14 \times 2.7 = 37.8 ).

Answer:

( 37.8 )
