I got this as a review problem and I'm not sure how to approach it. Imagine a landing craft approaching the surface of Callisto, one of Jupiter's moons. If the engine provides an upward force (thrust) of 3210 N, the craft descends at constant speed; if the engine provides only 2140 N, the craft accelerates downward at 0.32 m/s2. (a)...
A flowerpot is knocked off a balcony 26.7 m above the sidewalk and falls toward an unsuspecting 1.76 m tall man who is standing below. How close to the side walk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? Assume that the man below requires...

A vending machine company noted that bottled water sales for a 70 degree day were equal to 1,000 bottles when priced at $1.00. If the price is increased (decreased) by $0.01 then the sales fall (rise) by 10 bottles. If temperature rises (falls) by 1 degrees then the number of bottles sold increases (decreases) by 5 bottles. What is the...
The price elasticities for cigarettes by habitual smokers (addicts) and potential smokers (young people) are -0.2 and -3 in equilibrium. The government is considering levying a new 10% tax on cigarettes. (a) For each type of consumer, calculate the expected reduction in consumption from the new tax.
