A 16.0 - kg descends a slide 2.50 m high and reaches teh bottom with a speed of 2.25 m/s. How much thermal energy due to firciton was generated in the process?

for this I keep on getting 432.5 J but the back of the book tells me that the answer is 352 J and I do not see how to get this answer

I did the PE at the the top of the slide minus the KE at the bottom and got 432.5 J apparently I'm doing soemthing wrong thanks
