How much work would it take to push a # 6 kg # weight up a # 12 m # plane that is at an incline of # pi / 4 #?
Hypotenuse (h) = 12m
Angle of inclination (
Perpendicular (p) = ?
Hence, p = 8.5 m, which is the distance travelled.
Since work(W) is given by
W = F * S,
Where F = Force ( here weight) = 6 kg wt = 6 N
(Note kg wt, unlike kg, is same as Newton and is a unit of weight, not mass).
S is the distance traveled given by the perpendicular 8.5m
