14-6. When the driver applies the brakes of a light truck traveling 40 km/h, it skids 3 m before stopping. How far will the truck skid if it is traveling 80 km/h when the brakes are applied?
When the driver applies the brakes of a light truck traveling 40 km/h, it skids 3m before stopping. How far will the truck skid if it is traveling 80 km/h when the brakes are applied? Solve using kinetics. Do not use work and energy principles.
35. A car moving at 20 km/hr skids 10 m with locked brakes before coming to rest. How far will the car skid (on the same surface) if it is traveling at 80 km/hr?
A car of mass 875 kg is traveling 30.0 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.60 s in the positive -direction before coming to rest. (a) What is the car's acceleration? (b) What magnitude force acted on the car during this time? (c) How far did the car travel? [Ans: ()-536 m/s (b) 4690 N(c) 84,0 m]
A car of mass 772 kg is traveling 24.4 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.27 s in the positive x-direction before coming to rest. a). What is the car's acceleration (in m/s2)? (Indicate the direction with the sign of your answer.) b). What magnitude force (in N) acted on the car during this time? c). How far (in m) did the car travel?
A race driver traveling at a speed of 230 km hr on the straightaway applies his brakes at point Ά and reduces his speed at a uniform rate to 170 km hr at C in a distance of 160 + 150 = 310 m. Calculate the magnitude of the total acceleration of the race car an instant after itpasses point B a= 7.405 m/sec 2 470 m -150m にゅーー4. 160m.
A 1200-kg car going 30 m/s applies its brakes and skids to rest. If the friction force between the sliding tires and the pavement is 6000 N, how far does the car skid before coming to rest? Can you help me get the formula to use . Thanks
Problem 3. A car is traveling at a speed of 20 m/s when the driver applies the brakes. The car stops in 5 seconds. How far (in meters) does the car travel in that time? Assume the car's deceleration is constant.
1. A car is traveling at 36 km/hr and the driver puts on the brakes, bringing the car to rest in a time of 2s. What is the magnitude of the average acceleration of the car.
Texting while driving can distract you for several seconds. If you are traveling at 100 km/hr and are 90m behind someone (also traveling at 100 km/hr) who slams on his brakes at 3 m/s23 m/s2and it takes you 3 seconds to realize you now need to brake, how far apart will you be when you match his speed again if you brake at 12 m/s2?
