exactly like this, only use \(591\) and \(17\)

Answer 2

i got 565.2lb

Answer 3

do i used cos or sin

Answer 4

618

Answer 5

work = change in potential energy

(591) (L) = (m g) H

L is ramp length, (m g) weight), H ramp height
H = L sin (17)

(m g) = weight = 591 L / L sin(17) = 591 / .292 = 2021 lb

Figures to weigh a lot more than 591 lb, as this is
a gently sloping plane, thus much "mechanical advantage."

Assumes no friction, by the way.

Answer 6

so the answer is 2021

Answer 7

Answer 11

for the answer

Answer 12

is it right

Answer 13

eed help here plz

Answer 14

plz

Answer 15

2021 makes more sense than just 618, which is not much different from the force being used (591) on this gradual inclined lane.
