The distance required for a car to come to a stop will vary depending on how fast the car is moving. Suppose that a certain car traveling down the road at a speed of 20 m/s can come to a complete stop within a distance of 80 m. Assuming the road conditions remain the same, what would be the stopping distance required for the same car if it were moving at speeds of 10 m/s, 40 m/s, or 5 m/s...

A car that weighs 1.4×104 N is initially moving at a speed of 50 km/h when the brakes are applied and the car is brought to a stop in 15 m. Assuming that the force that stops the car is constant, find the magnitude of that force. Incorrect. Tries 5/20 Previous Tries Find the time required for the change in speed. Tries 0/20 If the initial speed is, instead, twice as great, and the car experiences the same force during...

2. A 2500 kg car is driving at 65.0 km/h on a horizontal level road. As it approaches a stoplight the light turns red so the brakes are applied as the car hits a patch ofice. With the brakes locked, the car travels 55.0 m before coming to a stop. A) What is the initial kinetic energy of the car? B) How much work is done by friction in stopping the car? c) What is the force of friction stopping...

A car travels in a straight line a distance of 8.4 km at an average speed of 70 km / h before stopping due to lack of fuel. Following this stop, the driver of this car walks for 30 minutes over a distance of 2.0 km to get to the nearest gas station. at. What is the total distance the driver has traveled between the beginning of the journey of her car and until he arrives at the gas station?...

Chapter 5 Q:6
A car that weighs 1.2 x 104 N is initially moving at a speed of 37 km/h when the brakes are applied and the car is brought to a stop in 20 m. Assuming that the force that stops the car is constant, find (a) the magnitude of that force and (b) the time required for the change in speed. If the initial speed is doubled, and the car experiences the same force during the braking, by...

4 (2.52). The minimum stopping distance for a car traveling at a speed of 30 m/s is 60 m, including the distance traveled during the driver's reaction time of 0.50 s. a) What is the deceleration of the car while braking? b) What is the minimum stopping distance for the same car traveling at a speed of 40 m/s with the same reaction time and deceleration?

H . While you are driving , your car collides with a tree. If you were to collide with the steering wheel, you would not come to a stop instantly; your center of gravity would travel 0.0 1 m before you were brought to a stop. In this case, you would feel 16 ,000 N of force from th e steering wheel – enough to break many ribs. If the force on you were 800 N or less, you would...

You're driving down the highway late one night at 20 m/s when a deer steps onto the road 36 m in front of you. Your reaction time before stepping on the brakes is 0.50 s , and the maximum deceleration of your car is 10 m/s2 . How much distance is between you and the deer when you come to a stop?

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...
