A police car, traveling a constant 100 km/h, is passed by a speeder. Precisely 1.1 s after the speeder passes, the policeman steps on the accelerator. The police car acceleration is 3 m/s2. The policeman overtakes the speeder after 6s, what was the speeder’s speed?
An object constantly accelerates from 4 m/s to 6 m/s for six seconds. How far does it go during those six seconds? An object constantly accelerates from v0 to vf during time interval t. Derive the expression for the distance traveled in terms of these three parameters.
Suppose you take a 3-hour trip in your car. For the first hour, you travel at a speed of 60 mi/hr. The weather suddenly gets very bad so that for the remaining 2 hours you travel at a speed of only 30 mi/hr. What was your average speed for the full three-hour trip? I
A burst water pipe in the city means you have to drive at a steady 12 km/h. Once past this obstacle, you speed up to 52 km/h in 10 s. You reach the freeway and, with the same acceleration, speed up for another 10 s to reach a higher speed. What is this final speed in km/h to one decimal place?
An advertisement for the newest model of a Mercedes sports claims the car can go from 0 to 60 miles per hour (mph) in just 3.3 seconds! a) How many meters per second (m/s) is 60 mph? b) In m/s 2 (sometimes written as m/s/s also, just so you know), what is the supposed acceleration of the sports car? c) Impressed by this claim, Sherry buys one. She hops into her new Mercedes sports car and steps on the gas. She’s an engineer and did the math later on; she discovered that her car’s acceleration is 6.7 m/s2 . i) Is her car’s acceleration faster or slower than the advertisement claims it should be? ii) In seconds, how long did it actually take for Sherry’s car to reach 60 mph
