Speed humps are to be placed on a street passing a primary school to try and ensure that vehicles do not travel faster than 50km/hr along the street. If a car goes over the humps at more than 25 km/hr then the passengers in the car will receive a nasty jolt. How far apart should the speed humps be placed in order to keep the speed of cars down to safe levels? Million thanks!
Well, you have an initial velocity (50 km/hr) and a final velocity (25 km/hr) and you want to calculate the distance travelled between the two points A and B where the car has those velocities. So how about you think about what other data is needed to do the calculation and then you tell me ....
