Hello I need help with my calculus 2 hw

1.

1. A bucket begins holding 25 kg of sand. The bucket is to be lifted to the top of a 25-meter tall building by a rope with density 0.2 kg/m. However, the bucket has a hole in it, and leaks 0.1 kgs of sand per each meter it is lifted. Find the work done lifting the bucket and rope to the top of the building. Use 9.8 m/s2 for gravity. 2. Evaluate the integral: 41r / t2 sin(2t)dt 0 Gather the work for both questions, combine them into one single pdf le and upload it here
