Consider a grey squirrel falling out of a tree to the ground.(a) If we ignore air resistance in this case (only for the sake ofthis problem), determine a squirrel’s velocity just before hittingthe ground, assuming it fell from a height of 3.0 m. (b) If thesquirrel stops in a distance of 2.0 cm through bending itslimbs, compare its deceleration with that of the airman in theprevious problem
(c) Tests reveal that a normal driver takes 0.75 s before he or she can react to a situation to avoid accident or collision. It takes about 3.00 s for a driver with having 0:10% of alcohol in his syst em to do the same. If such drivers are travelling on a straight road at 44:00 ft=s and their cars decelerates at 0:68 m-s, ded ermine the shortest st opping distance, d, for each from the moment they see the pedestrians. Refer to Figure 1. [1 m = 3.2808399 ft] 2

In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.
