No Need To Trade Accusations - Case Study Example agree to the paper, to begin, we note that according to the work energy principle, its possible to calculate the velocity v of a car coming to a halt given up the cars weight and the coefficient of friction. In this case, the velocity can be got by using the formula. This gives a velocity of approximately 17.68 this translates to 38.0279 miles per hour way above the speed bound of 35 miles per hour that the humble township of West Trenton recommends for its citizens. Sandys car was pushed for a distance of 9m or 30 feet and since we know the final velocity of the wagon train which was given as 25miles per hour by the police officer we can use this to calculate the weight or the mass of the van by considering that this van transferred energy to sandys car and this can be treated as work done. The van must have had a mass given by =176289 and which translates to a mass of 3101.50 kg 0r 6837.64lbs this is quite heavy. We can use this information to calculate the deceleration of the van before strike sandys car and from this the initial velocity of the van. And a speed of 17.25m/s and which is a speed of 38.587 miles per hour.
