A 5.50-kg birthday present is sliding down a curved hill with an initial speed of 3.80 m/s. While it is sliding to the bottom of the hill, friction takes away 100 Joules of energy from the present. How fast is it moving when it reaches the bottom? Yi = 2.00 m Yf = 0.00 m

Question
**Problem Statement:** A 5.50-kg birthday present is sliding down a curved hill with an initial speed of 3.80 m/s. While it is sliding to the bottom of the hill, friction takes away 100 Joules of energy from the present. How fast is it moving when it reaches the bottom? **Diagram Explanation:** The image shows a curved hill with a box, representing the birthday present, sliding down it. The hill has an initial height (y₁) of 2.00 m at the starting point of the descent and a final height (y_f) of 0.00 m at the bottom. The problem involves calculating the final speed of the present as it reaches the bottom of the hill, accounting for the energy lost due to friction.
