16) You are in the left lane (speeding) at 40 m/s when you notice a police car ahead of you traveling at 30 m/s (the speed limit). When you are 45 m apart you start decelerating at 1.0 m/s2. Will you pass the police car and get a ticket? 17) A car is traveling at 25.0 m/s approaching a bicyclist moving at 7.0 m/s in the same direction. There is 75 m between them when the driver hits the brakes....

A Review Constants Periodic Table Part A You are driving your 1400 kg car at 19 m/s down a hill with a 5.0° slope when a deer suddenly jumps out onto the roadway. You slam on your brakes, skidding to a stop. How far do you skid before stopping if the kinetic friction force between your tires and the road is 1.1x104 N ? Solve this problem using conservation of energy. Express your answer with the appropriate units. μΑ 2)...

You are driving along the highway at a steady speed of 90 km/h when another car decides to pass you. At the moment when the front of his car is exactly even with the front of your car, and you turn your head to smile at him, do the two cars have equal velocities? Draw a position graph to describe the motion of two cars.

020 (part 1 of 3) 10.0 points You are driving at the speed of 34.8 m/s (77.862 mph) when suddenly the car in front of you (previously traveling at the same speed) brakes and begins to slow down with the largest deceleration possible without skid- ding. Considering an average human reaction, you press your brakes 0.576 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.722 between both...

A police officer with a radar gun clocks a speeding car as traveling 74 km/h along a country lane. Assume that the police officer starts accelerating 5 seconds after the speeding car passes by and in order to catch up with the car. Assume the car travels at the same speed for 6 seconds, then slows down to 77 % of the original speed. What minimumacceleration will allow the officer to catch up with the car in 25 seconds? Express...

Constants I Periodic Table - Part A You're an electrical engineer designing an alternator (the generator that charges a cars battery). Mechanical e diameter rotating coil, and you determine that you can fit 250 turns in this coil. To charge a 12-V battery, you need a peak output of 10 V when the alternator is rotating at 1800 rpm. What do you specify for the alternators magnetic field? Express your answer to two significant figures and include the appropriate units....
