3. How much work is necessary to lift 10 kg 5m in the air? 1) 10N
3) 490 J
2) 50 J
4) 4900 J

I'm not 100 percent sure but I have had a question very similar to this and I think 2.)50 j

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
