I just calculated the upthrust force experienced by the block

I think I did one about power and work done,but apart from that I don’t know lol,it was a hard hard question which confused me a lot!

How did you caculate it?

Well i'm not sure if its right, but if the block is moving at a constant speed but the force increases when the block is being lifted out the water then we can tell that the upthrust force was helping the crane lift the block. The force the crane applied to lift the block when it was submerged in water was 102KN, and the force when the block was out of the water was 170KN (when upthrust force is no longer acting on the block). So i thought you can take away these forces the crane applied on the block to get the upthrust force. 170 - 102 = 68KN, which I think is the upthrust force experienced by the block when in the water

Ah of course. thanks. Hopefully I'l still pick up like 3 marks lol. Any idea how to calculate the weight of the block too, I guess this calculation probably isnt needed though is it?

Don't think that would be possible unless we knew the speed at which the block was being lifted at
