Consider a herd of lemmings running up a hill towards a cliff. Suppose the hillside they are running on is at a 30° incline, the lemmings’ speed is 5 km/h, and that a 1 km/h wind is blowing horizontally towards the cliff.
Consider the lead lemming, shown below. Draw the vector representing this lemming’s travel up the hill; draw the vertical and horizontal component vectors as well. Label the direction and magnitude of all three vectors on your sketch. Show all calculations.
Consider what happens at the moment the lemming runs off the edge of the cliff. Sketch the lemming’s run vector and the wind vector. If we combine these vectors, what are the magnitude and direction of the resultant vector? (you can ignore gravity and any other complicating factors here)
Consider what happens 10 seconds after the lemming has run off the cliff. Sketch the lemming’s run vector, the wind vector, and the 98 m/s (5.88 km/h) downward velocity due to gravity (recall, acceleration due to gravity is 9.8 m/s per second). If we combine these vectors, what are the magnitude and direction of the resultant vector? (you can ignore reality and any other complicating factors here).

Read the excerpt from the strange case of dr jekyll and mr. hyde what do dr. jekyll's thoughts reveal about him in this excerpt? [t]he inmates of my house were locked in the most rigorous hours of slumber, and i determined, flushed as i was with hope and triumph, to venture in my new shape as far as to my bedroom. i crossed the yard, wherein the constellations looked down upon me, i could have thought, with wonder, the first creature of that sort that their unsleeping vigilance had yet disclosed to he is jealous of those who can sleep through the night. he is revered for his scientific advances. he is interested in studying the movements of the stars he is proud and enthusiastic about his initial results.

Mariano delivers newspaper. he always puts 3/4 of his weekly earnings in his savings account and then divides the rest equally into 3 piggy banks for spending at the snack shop, the arcade and the subway
