Time (t) = 0.25 second
Speed of car (v) = 85km/h = 85 x 5/18 = 23.61 meter per second
Than distance travelled by car in this time period (d) = V x t = 23.61 x 0.25
Distance = 5.90 meter

During a hard sneeze, your eyes might shut for 0.42 s. If you are driving a car at 85 km/h during such a sneeze, how far does the car move during that time? Please, show all of your work. This means show step by step how you arrived at your answer(s). Include any equations or formulas used to arrive at the answer(s). Thanks!
Chapter 02, Problem 001 During a hard sneeze, your eyes might shut for 0.56 s. If you are driving a car at 75 km/h during such a sneeze, how far does the car move during that time? the tolerance is +/-2% We were unable to transcribe this imageWe were unable to transcribe this image
You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop? A rock is tossed straight up with...
please tell me the answer and process. Thank you!!
ou're driving down the highway late one night at 30 m/s when you spot a deer in brakes is 0.35s and the maximum deceleration of your car is 8.0 m/s. the road some distance in front of you. Your reaction time before stepping on the a) What is the total distance covered by your car from the time you first see the (8pts) deer to when you are at a complete...
Reaction time is .19 seconds
(c) You are driving on the highway at 60 mph behind another vehicle driving at the same speed. How far does your car move over a time interval equal to your reaction time? The "two-second rule" states that you should stay at least two seconds behind any vehicle that is directly in front of you. Why is this time so much larger than your reaction time?
If you are driving 90 km/h along a straight road and you look to the side for 2.7 s , how far do you travel during this inattentive period?
You are driving to the grocery store at 20 m/s. You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. a. How far are you from the intersection when you begin to apply the brakes? b. What acceleration will bring you to rest right at the intersection? c. How long does it take you to stop?
Part A When you sneeze, the air in your lungs accelerates from rest to 145 km/h in approximately 0.30 s. What is the acceleration of the air in m/6 Express your answer to two significant figures and include the appropriate units.
You are driving to the grocery store at 20 m/s . You are 1.10×102m from an intersection when the traffic light turns red. Assume that your reaction time is 0.79 s and that your car brakes with constant acceleration. A) How far are you from the intersection when you begin to apply the brakes? B) What acceleration will bring you to rest right at the intersection? C) How long does it take you to stop after the light turns red?
You are driving at 30m/s and hit your breaks, skidding to a stop. The static coefficient of friction between your tires and the road is μs = 0.7. The mass of your car is 1500 kg. a) What is your initial kinetic energy right before you hit the breaks? b) What is the magnitude of the static friction force acting on the car? c) Does the friction do positive or negative work on the car? Explain your reasoning. d) Use...
