a 0.5 kg book falls from a shelf. at 0.1 s, the book is 0.75 m above the ground. what is the potential energy of the book? $e_p = ? j$ $e_p = mgh$ for gravitational acceleration, use $g = 10 m/s^2$. 1.25 j 2.5 j 3.75 j

Answer

Explanation:

Step1: Identify given values

We have mass ( m = 0.5\space kg ), gravitational acceleration ( g = 10\space m/s^2 ), and height ( h = 0.75\space m ).

Step2: Apply potential energy formula

The formula for gravitational potential energy is ( E_p = mgh ). Substitute the given values: ( E_p = 0.5\times10\times0.75 )

Step3: Calculate the result

First, multiply ( 0.5 ) and ( 10 ): ( 0.5\times10 = 5 ). Then multiply the result by ( 0.75 ): ( 5\times0.75 = 3.75 ).

Answer:

3.75 J
