Two snow-covered peaks are at elevations of 862 m and 741 m above the valley between them. A ski run extends from the top of the higher peak to the top of the lower one as shown in the following figure 5. 862 m 741 m A skier starts from rest on the higher peak. At what speed would he arrive at the lower peak if he just coasted without using the poles? Assume icy conditions, so that there is...
Please help solve all parts of this problem as it is a review
question for a upcoming test. I already have answers but am
interested in other methods to find solutions. If possible could
you work it out on paper, I can follow it alot easier. I will leave
ratings on answers.
Thanks

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
N
(b) If the required force is directly proportional to speed, how
many...
