(i) The car starts from rest. From time = 0 to time = 15 s, the car has a constant acceleration to a speed of 28 m/s. From time = 15 s to time = 32 s, the car has a constant speed of 28 m/s. From time = 32 s, the car has a constant deceleration of 2.0 m/s until it comes to rest. On Fig. 1.1, draw the graph, using the space below for any calculations.

Challenge A woman becomes incredibly ill after attending a baby shower. After a day of non-stop vomiting, she goes in to the doctor and is diagnosed with Salmonellosis, a type of food poisoning caused by an infection from the Salmonella bacteria. The doctor prescribes her with ampicillin. The antibiotic helps for a few days, but then the symptoms return. She goes back to the doctor and is prescribed a different antibiotic ciprofloxacin. This fails to provide any relief, not even for a short amount of time like the first antibiotic did. Describe, in detail, what most likely happened, from an evolutionary standpoint

A flashlight can be made that is powered by the induced current from a magnet moving through a coil of wire. The coil and magnet are inside a plastic tube that can be shaken causing the magnet to move back and forth through the coil. Assume the magnet has a maximum field strength of 0. 05 T. Make reasonable assumptions and specify the size of the coil and the number of turns necessary to light a standard 1-watt, 3-V flashlight bulb

Computer simulations are used to predict the weather. A computer simulation is a kind of model. Large amounts of data are entered into the computer. Then the computer performs complicated calculations with the data. The result is a prediction about what the weather might be like in the coming hours or days. Why are computers widely used for modeling weather systems?
