a)How much work is required to lift a 35-kg object from the ground 3.0 m into the air?
b) How much gravitational potential energy did this object gain?
So 35 x 9.8 = 343 N
343 x 3.0 = 1029 J
Is that the answer to A or B, I'm a bit confused
lol, we have this on a review sheet Aswell. how students from different years been answering this is just hilarious.
343 N for A and 1029 J for B
Fg=M x g Is that right cause i am doing a test
=35 kg x 9.8N
=343N
343 x 3.0=1029J
So does a)343N and b)1029J
?????????????????????????????????????????????????????????????
