Answer:
The change in energy is 1.023 J.
Explanation:
The formula for Kinetic Energy is [tex]\frac{1}{2} mv^{2}[/tex]
The formula for Potential Energy is [tex]mgh[/tex]
In the above question, the hammer has an initial Kinetic Energy which hits the anvil loses some energy and rises up to gain potential energy.
Initial Kinetic Energy= [tex]\frac{1}{2} * 3 * 1.5^{2}[/tex]
=3.375 J
Potential Energy it gains after rising the particular height= 3*9.8*0.08
=2.352 J
Therefore, the difference in energy is 1.023 J.
