Red line is x-t curve for car's motion. ( straight line sloped upward)
Blue curve is x-t curve for trooper's motion. (an upward shaped curve whose slope increases as the displacement x
increases )
Practice it:
Velocity of car (constant)
The car travels a distance in time
Then the car travels a distance in time .
After time , the trooper starts from rest with an acceleration . In time trooper travels a distance and overtakes car.
The distance traveled by trooper in time is equal to total distance covered by car in time
That is
solving above quadratic equation
a) Time taken by trooper to overtake the car is
b) Speed of trooper while he is overtaking car is

Please help me out as much as possible, I'm stuck, please try and get to the ones you can(: Thanks bunches ▼ 6:01 ← PHYS-1101-02 Lect 50.7 m/s LEARN MORE REMARKS The trooper, traveling about twice as fast as the car, must swerve or apply his brakes strongly to avoid a collision! This problem can also be solved graphically by plotting position versus time for each vehicle on the same graph The intersection of the two graphs corresponds to the...
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...
A car traveling at a constant speed of 29.0 m/s passes a trooper hidden behind a billboard. One second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 2.90 m/s2. How long does it take the trooper to overtake the speeding car?
Use the worked example above to help you solve this problem. A car traveling at a constant speed of 27.3m/s passes a trooper hidden behind a billboard, as in the figure. One second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.98 m/s2. (a) How long does it take the trooper to overtake the speeding car? s (b) How fast is the trooper going at that time? m/s

need help with ANALYZE PART A AND B and FINALIZE EXPLORE A car is moving with constant acceleration along a straight road (A) Determine how the velocity and the displacement of the car vary with time if the car is initialy moving to the right with a speed of 9.0 m/s and has an acceleration to the right of 1.7 m/s (B) Determine the velocity as a function of time when the velocity is instead initially to the right and...
1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...
