Jack and Jill are doing a physics lab. They apply a 15 Newton force to a 3 kg cart to pull it up an inclined plane at a constant speed. The plane in inclinee at a 30 degree angle. Jack and Jill are exerting a force on the cart which is parallel to the inclined plane in order to displace it 2.0 meters along the incline to a final height of 1 meter. During this lab, how many Joules of work was done on the cart?

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

false
