Answer:
6 J
Explanation:
Gravitational Potential Energy can be calculated using the formula:
PE = mgh
where m is mass of object in <em>k</em><em>g</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>g is the gravitational acceleration of 10 m/s^2
h is the height at which object is thrown in <em>m</em><em>.</em>
Hence, by substituting in the values, we get:
GPE = (4.0)(10)(0.15)
<u>6</u><u> </u><u>J</u>
Hence, the potential energy is <u>6</u><u> </u><u>J</u><u>.</u>
