Hossein is a weightlifter. His best lift in training is a bar with a mass of 250kg. He does 5000 j of work on the bar with a mass of 250kg when he lifts it.
The gravitational field strength (g) on earth is 10 N/kg
I am trying to calculate the weight of this 250kg mass, and how high Hossein lifts the bar.
Weight = 2,500N (I think) but canāt work out how to get the height lifted in metres..
Can anyone help in working this out, showing workings so I can work it through with my daughter.
Many thanks
