You pick up a 7kg bag and lift it to a height of 0.7m. You proceed to walk down the hallway 25m carrying the bag. You stop and lift the bag from 0.7m to a height of 0.95m. You continue to walk another 10m and then stop for 75s to talk to your friend.
How much work did you perform on the bag throughout the whole scenario?
If it took you 0.95s to lift the bag to a height of 0.7m, how much power did you generate?
