You are driving on a straight road at exactly 21.8 miles per hour when you see a child run out in front of your car, chasing a ball. You push the brakes hard, which results in an acceleration of exactly -36000 miles/hour2. The child freezes in panic and you cannot swerve to avoid the child because there are cars parked on both sides of the street. How many feet does your car travel before it comes to a complete stop?...
A 1000kg car with a velocity of 25m/s brakes to a stop. how many calories of heat are generated by the brakes as a result?
51. Safety research Under ideal conditions, if a person driving a car slams on the brakes and skids to a stop, the length of the skid marks (in feet) is given by the formula L0.000 013 3xy2 where x is the weight of the car (in pounds) and y is the speed of the car (in miles per hour). What is the average length of the skid marks for cars weighing between 2,000 and 3,000 pounds and traveling at speeds...
Your car gets 33 miles per gallon, you drive an average speed of 44 miles per hour. How much gas do you use in an hour?33/44? or 44/33
Consider someone driving down the highway at 70 miles per hour (31.3 m/s). The total mass of the driver and their car (as well as everything else in the car) is 1300kg. A) How much work must friction do to make the car stop? I got −6.37×10^5 J B) A tree suddenly falls on the highway 60m in front of the car, and the driver just barely manages to stop before hitting the tree. What is the magnitude of the...
You are driving at night on a highway at a speed of 18.2m/s. All of a sudden you see a deer in the road 38.3 m ahead. a. If you can slow down at a maximum rate of 4.50 m/s2, what reaction time is required to avoid hitting the deer? b. If your reaction time is actually 0.300s, how fast will you be traveling when you hit the deer?
Gas mileage actually varies slightly with the driving speed of a car (as well as with highway vs. city driving). Suppose your car averages 31 miles per gallon on the highway if your average speed is 54 miles per hour, and it averages 29 miles per gallon on the highway if your average speed is 69 miles per hour. Answer parts (a) and (b) below. a. What is the driving time for a 3000-mile trip if you drive at an...
