Homework Statement A helicopter is used to fill buckets with water to drop on fires. The bucket is a hemisphere with a diameter of 2 meters and a mass of 25 kg. The helicopter lowers the bucket into a lake or reservoir to fill it a) What is the weight of a bucketful of water? [/B]Homework...

Okay, thank you. I understand what you're telling me. I was just curious as to why I have seen some people refer to canceling out the masses when looking for acceleration of one object. But you've answered my question so thanks!

Also, thank you for your response. I appreciate it.

So, You're saying a = m1gsin(theta)-m(ofblock2)gsin(theta)/m(of blk1)+m(blk2) would be the correct approach. Could you be able to tell me when it would be appropriate to cancel out the masses? in the mgsin(theta) or mgcos(theta)= ma equation only leaving gsin(theta)= a ?
