1.7.01-001According to the rule of thumb, how long is the reaction distance at a speed of 50 km/h?↗1.7.01-002According to the rule of thumb, how long is the braking distance for normal braking from 80 km/h?↗1.7.01-003According to the rule of thumb, how long is the braking distance for emergency braking from 100 km/h?↗1.7.01-004According to the rules of thumb, how long is the stopping distance for normal braking from 70 km/h?↗1.7.01-005According to the rules of thumb, how long is the stopping distance for emergency braking from 50 km/h?↗1.7.01-006You are driving at 50 km/h and are distracted, so your reaction time is twice as long as usual. According to the rule of thumb, how long is your reaction distance?↗1.7.01-007You double your speed from 40 km/h to 80 km/h. According to the rule of thumb, how many times the original braking distance do you now need?↗1.7.01-008You are driving three times as fast as before. By what factor does your vehicle's kinetic energy increase?↗1.7.01-009With the same reaction time, what does the length of the reaction distance depend on?↗1.7.01-010What does the length of the braking distance depend on?↗1.7.01-011In terms of force, an impact at 50 km/h against a solid obstacle is roughly equivalent to a fall from what height?↗1.7.01-012You drive through a bend at twice the speed. How does the centrifugal force change?↗1.7.01-013The bend ahead of you gets tighter and tighter (smaller radius). How does the centrifugal force change if your speed stays the same?↗1.7.01-014A child runs onto the road 15 m ahead of you. According to the rules of thumb, what is correct?↗1.7.01-015What is correct about the braking distance on a wet or slippery road?↗1.7.01-016The wheels of your vehicle lock when braking (no ABS). What is correct?↗
