If the speed of a truck is reduced from 26.7m/s to 6.7m/s within a distance of 800m. Find the time the break were applied and how much longer it would take before coming to a rest |

Answer» SPEED =26.7-6.7 =20.0m/sec THEREFORE you can ALSO WRITE it as =20m/sec distance=800m time=? therefore, speed=distance/time 20=800/time time=800/20 time=40sec |
