In an auto accident, a car hit a pedestrian and the driver then slammed on the brakes to stop the car. During the subsequent trial, the driver's lawyer claimed that he was obeying the posted speed limit 60.0-kph, but that the legal speed was too high to allow him to see and react to the pedestrian in time. You have been called in as the state's expert witness. Your investigation of the accident found that the skid marks made while the brakes were applied were 86.0 m long, and the tread on the tires produced a coefficient of kinetic friction of 0.30 with the road. a. In your testimony in court, will you say that the driver was obeying the posted speed? You must be able to back up your conclusion with clear reasoning because one of the lawyers will surely cross-examine you. b. If the driver's speeding ticket were 200 pesos for each kilometer per hour he was driving above the posted speed limit, would he have to pay a fine? If so, how much would it be?
The pilot of a jet transport brings the engines to full takeoff power before releasing the brakes as the aircraft is standing on the runway. The jet thrust remains constant, and the aircraft has a near-constant acceleration of 0.32g. If the takeoff speed is 245 km/h, calculate the distance s and time t from rest to takeoff. Answers: m
Cheetahs can accelerate to a speed of 21.8 m/s21.8 m/s in 2.55 s2.55 s and can continue to accelerate to reach a top speed of 28.6 m/s28.6 m/s . Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +?+x direction point in the direction the cheetah runs. Express the cheetah's top speed ?topvtop in miles per hour (mi/h)(mi/h) . vtop=63mph     Starting from a crouched position, how much time ?acceltaccel does it take a cheetah to reach its top speed and what distance ?d does it travel in that time?   taccel=3.35 d=47.98     If a cheetah sees a rabbit 123.0 m123.0 m away, how much time ?totalttotal will it take to reach the rabbit, assuming the rabbit does not move and the cheetah starts from rest?   The last question is where I am stuck, I don't know if I'm using the wrong formula or what.
