c.1.9 × 10^2 joules
d.2.8 × 10^2 joules

Answer 1

what is defined as work?

Answer 2

im not sure

Answer 3

W = force * distance
How do you calculate force?

Answer 4

mass x acceleration

Answer 5

yeah. and you know the distance. so how can you go about getting the force

Answer 6

i dont know the acceleration

Answer 7

we're talking about lifting the object, so the acceleration is that of gravity
