A car going 35 m/s passes a truck at stop. The truck starts driving and follows the car and accelerates to 45 m/s after driving 220 m. How long does it take for the truck to catch up to the car, if the car never changes speed.
Problem A car traveling at a constant speed of 24.0 m/s passes a trooper hidden behind a billboard, as in Figure 2.17. One second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.00 m/s. (a) How long does it take the trooper to overtake the speeding car? b) How fast is the trooper going at that time? Figure 2.17 (Example 2.5) A speeding car passes a hidden trooper. When does...
2.10 A car is going 35 m/s when the driver applies the brakes. a) If the braking acceleration is −5.7 m/s2 , how far will the car go as its velocity drops from 35 m/s to 22 m/s? b) How much time will the change from 35 m/s to 22 m/s take? 2.11 As hockey puck slides to a stop, it goes 40 m across the ice in 3.7 s. a) What was the initial velocity of the puck? b)...
A car traveling 34.0 m/s overtakes another car going only 22.0 m/s. When the faster car is still behind the slower one, it sounds a horn of frequency 1100.0Hz. What is the frequency heard by the driver of the slower car?
A car traveling 40.0 m/s overtakes another car going only 25.0 m/s. When the faster car is still behind the slower one, it sounds a horn of frequency 1600.0Hz. What is the frequency heard by the driver of the slower car?
John’s car is 0.50 mile behind Allen’s car while John is moving at 70 mile/hour and Allen 60 mile/hour. a) If John doesn’t accelerate, how long does take him to catch up (right next to) with Allen? b) If John would like to catch up with Allen in 10 second, what kind of acceleration that John needs to get from his car? At the moment when John’s car catches up with Allen’s, how far has John traveled from...

6. A firetruck going at 40m/s with a 900Hz siren is approaching a car from behind. The car going 20m/s (Both firetruck and car are initially going in the same direction). What is the frequency experienced, fo, for the person in the car? a, 900 Hz b. 925 Hz ?. 853 Hz d. 959 Hz e. 1001 Hz 7. Using the exact same speeds as in Problem #6 above and the same siren frequency, what is the frequency experienced, fo,...
7 A bus is traveling east at a constant speed of 28 m/s. A car is 200 m behind the bus and begins to accelerate east at 4 m/s2 starting from an initial speed of 13 m/s. How long will it take the car to catch up to the bus?
