1.) Landing with a speed of 79.6 m/s, and traveling due south, a jet comes to rest in 965 m. a.) Assuming the jet shows with constant acceleration, find the magnitude and direction of its acceleration. B.) to the south or to the north?
2.) a firefighter slides down a pole in a fire station with an acceleration of 8.2 m/s2. If the firefighter starts at rest and slides for a distance of 3.7 m , what is his final speed?
3.) a baseball player is dashing toward home plate with a speed of 3.0 m/s when she decides to hit the dirt. She slides for 1.5 s , just reaching the plate as she stops. A. What’s her acceleration? (Assume her running direction is the positive direction.) B. How far does she slide?
4.) when you see a traffic light turn red, you apply the brakes and stop with constant acceleration. If your initial speed was 28 m/s , what’s your average speed during braking?

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
