physics What is the average power exerted by on Marilyn during this trip? What is the total work done by all forces acting on Marilyn during this trip? Eddie Munster (m = 30 kg) climate a of height 23 m in 160 seconds. What is the average power needed for this climb? Grandpa can turn into a giant bat (m = 3.1 kg), but then he is blind as a bat, and he flies right into a wall. He contacts the wall with a speed of 7 m/s, and then falls straight down to the floor. If he was in contact with the wall for 0.6 s, what was the magnitude of the average force exerted on Grandpa by the wall? Five Munster family members try to slide Grandpa's lightning generating equipment into a back room. The object moves in the direction indicated, subject to the five forces shown. As always for such drawings, the length of each arrow is proportional to the magnitude of the force. The grid is provided only for your convenience. Rank the work done by the forces from most negative to most positive with no spaces, using

Explanation / Answer

WORK DONE=FSCOS(THETA)

work done by force A

WA=NEGATIVE( ANGLE IS MORE THAT 90)

WB=POSITIVE(LESS THAN 90)

WC=POSITIVE

WD=ZERO(ANGLE=90)

WE=NEGATIVE(ANGLE=180)

C>B>D>E>A
