Just before a potential traffic accident one car is traveling at 128 km/h when the driver fully applies the brakes (so that he may avoid an accident) by producing a constant deceleration of 5 m/s2. You must find the distance traveled by the car before the car comes to a full stop. Equivalently, this is the distance from the place where the driver must hit the brakes, to the place where the car will fully stop right before/ at the potential traffic accident. find correct linear function for velocity, function of time t, with some constant, C, the intercept find correct value of the constant intercept C in part (a) find correct quadratic displacement function of time t find correct time until full stop of the car, and find correct distance
Car A is 80km east of Car B and begins moving west at 40km/h. At the same moment, Car B begins to move north at 70km/h. What is the closest distance in km, the cars will be from each other AND at what time t, in hours, will that distance occur?

in his model for storage and shipping costs for a manufacturing process, a researcher develops the following formula c=100(100+9x+144/x), where C is the most storage and transportation for up to 100 days of operation and load of material is moved every "x" days. Find the value of x for which C is a minimum.

A tank contains 100 gal of brine in which 50lb of salt is dissolved. Brine containing 2lb/gal of salt runs into the tank at the rate of 3 gal/min; and the mixture, assumed to be kept uniform by stirring, runs out the rate of 2 gal/min. Assuming that the tank is sufficiently large to avoid overflow, find the amount of salt in the tank as a function of the time t. When will the concentration of salt in the tank reach 3/2 lb/gal? How much salt is in the tank at the end of 30 mins?
