In the aftermath of a car accident, it is concluded that one driver slowed to a halt in 16 seconds while skidding 1075 feet. If the speed limit was 45 miles per hour, can it be proved that the driver had been speeding?(Hint: 45 miles per hour is equal to 66 feet per second.)We can guarantee that at some time from when the driver first pressed on the brake to when the car came to a complete stop the car was traveling ___________ mph.Therefore we __________ (can/can not) conclude that the driver was speeding from the information given.
Two stationary patrol cars equipped with radar are 5 miles apart on a highway, as shown. As a truck passes the first patrol car, its speed is clocked at 55 miles per hour. Four minutes later, when the truck passes the second patrol car, its speed is clocked at 50 miles per hour. Prove that the truck must have exceeded the speed limit (of 55 miles per hour) at some time during the 4 minutes
Prove the second line only.
A man flies a small airplane from Fargo to Bismarck, North Dakota --- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1.5 hours. What is the plane's speed in still air, and how fast is the wind blowing?

(a) The service elevator at AR Hector Financial Complex has a maximum capacity of 2870 lbs.If the elevator operator weighs 205 lbs and has to move hundreds of boxes from the ground floor tothe Penthouse, if each box weighs 65 lbs, what is the maximum number of boxes that can besafely conveyed on the elevator on each trip? (b) The borough of Pan Sherzando charges homeowners $75.24 per month plus $3.86 per1000 litres for water usage in excess of 10,000 litres. In 2019 one homeowner’s monthlybill ranged from $137.00 to $245.08. Find the range for the water used by that homeowner.

the flight from Seattle to New York, with a tailwind, takes 5 hrs 15 min, and the return flight take 6 hrs 35 minutes. Since the flight time includes time to taxi from and to the gate, we should subtract 45 minutes from each time to account for this. Not shown, I was able to find out the plane was scheduled to fly a 2395 mile flight path. Assuming the plane and wind speeds are constant during both flights, estimate the wind speed, to 1 decimal place.
Two cars, one going east with the speed of 45 mph while the second car heading south at 70 mph, are traveling toward a common point of intersection. At what rate are the cars approaching each other when the first car is 1 km and the second car is 3 km from the intersection? Will they collide at the intersection? Prove your answer.
(a) The service elevator at AR Hector Financial Complex has a maximum capacity of 2870 lbs. If the elevator operator weighs 205 lbs and has to move hundreds of boxes from the ground floor to the Penthouse, if each box weighs 65 lbs, what is the maximum number of boxes that can be safely conveyed on the elevator on each trip?
A prisoner, 1.80 meters in height, was discharged in consideration due to his advanced in age. In order to receive full pardon, he must run as fast as he can towards the country border 100 meters from the prisoner's position to be totally free. Unknown to the prisoner, he was not meant to be discharged alive, due to the heinous crimes he has committed. An archer with an exceptional accuracy, hidden from the prisoner, was 15 meters behind him. As soon as the prisoner started running at a rate of a = 0.012t m/s², an arrow was released 30 seconds after the prisoner moved from rest, from a 2-meter high at an angle of 30 degrees above horizontal aiming at the middle of his body for a sure kill (neglect air resistance). a. What should be the initial velocity of the arrow if the prisoner was dead before reaching the country border? b. What was the distance from the country border to the dead prisoner?
