How road safety has changed over the years Why Speed Limits Have Changed During the last 100 years speed limits have changed in the UK‚ now in residential areas speed limits are generally 20mph to 30mph and on main roads the speed limit is 40mph. On the motorways the speed limit is raised to 70 mph. The first speed limit was 1865; this speed limit was 2mph in built up areas such as cities‚ towns and villages. This was then raised to 20mph and large fines were put in place for speeding and

SOLUTION TO HOMEWORK PROBLEMS Chapter-4: MOTION IN TWO DIMENSIONS 1 A particle starts from the origin at t = 0 with a velocity of 6.0[pic] m/s and moves in the xy plane with a constant acceleration of (-2.0[pic] + 4.0[pic]) m/s2. At the instant the particle achieves its maximum positive x coordinate‚ how far is it from the origin? [pic] 2 At t = 0‚ a particle leaves the origin with a velocity of 5.0 m/s in the positive y direction. Its acceleration is given by [pic] = (3.0[pic] - 2.0[pic])

Drivers Do other drivers piss you off? In my experience‚ there are three kinds of drivers in this world; the inconsistent driver‚ the over cautious driver‚ and the alert Driver. There is the inconsistent driver‚ this type of driver can seem to be fairly unpredictable on the road‚ with their tailgating and speeding‚ this person is the most hazardous to themselves and other travelers. Then there is the over cautious driver‚ who is just as easy to spot as the inconsistent driver. They are normally

The question‚ "Do speed limits matter?" hardly seems worthy of an answer. Insurance companies‚ police agencies‚ state transportation departments‚ and national safety organizations would have us believe that speed limits are a critical component of traffic regulation. Without those numbers on the signs and radar-wielding highway patrols‚ the entire system would self-destruct. This belief is based on several dubious precepts‚ none of which have ever been proven or justified. The most basic of

Learning‚ Perception The advert begins with Prof. Ian Johnston narrating the following simulation comparing two identical cars travelling at different speeds and the rate of their respective braking speeds. One car was initially travelling at 65 km/h and the other car travelling at 60 km/h when a change in the road ahead appears ahead a truck blocking their path. The time between when the drivers initially react and the time they come in contact with the truck the car travelling at 65 km/h collides

WHAT IF EARTH STOPS SPINNING? As we all know‚ planets spin. Our solar system was formed billions years ago from a spinning cloud of gas and dust. Nowadays‚ the Earth is turning at more than 16 hundreds kilometers an hour‚ bus it’s gradually slowing down about two seconds every one hundred thousand years. BUT WHAT WOULD HAPPEN IF THAT SLOWDOWN SPEEDS UP? If the speed of rotation were reduced by about one kilometer per hour‚ traffic air would face serious consequences. Most commercial aircrafts

Steps to be taken for Preventing Road Accidents 1. Most important method to bring down accidents is strict enforcement of speed limits. 90 % of accidents can be avoided by strict enforcement of speed limits. 2. Heavy Penalty should be imposed on ALL those who cross speed limits. If this is strictly implemented‚ nobody will dare to go at high speed. 3. Existing speed limits should be brought down further. 4. Heavy penalty should be imposed for those who cause accidents

Miles and Snow have produced a typology of business-level strategies. As opposed to corporate-level strategy‚ i.e.‚decisions related to what businesses should the firm be in‚ business-level strategy is related to how the organization competes in a given business (Hambrick‚ 1983). Miles and Snow proposed that firms in general develop relatively stable patterns of strategic behaviour in order to accomplish a good alignment with the perceived environmental conditions. Their typology involves four strategic

‘So What’ Miles Davis Solo Analysis Miles Davis’ solo is very minimalistic mainly using crotchet and quaver rhythms throughout with the occasional triplet or semiquaver grace note. For the A sections of the first chorus he bases phrases around the minor pentatonic scale. He develops his opening motif (bar 2 of A1) in bar 4-7 returning to the root (E) in between each ascending then descending phrase going up to the 7th (D) in the final variation of the motif. The phrase lengths are irregular; Davis
