Concept explainers

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.

A cop spots a car speeding at 106 mph and immediately starts after the perpetrator. How fast at minimum does the cop need to go to catch up to the perpetrator within 5 miles (i.e. before the perp drives more than 5 miles), if the perpetrator was 0.5 miles ahead of him originally?Round your answer to nearest mile per hour.
At the scene of a car accident, the forensic investigator measured the skid marks from one of the vehicles to be 83 m long. He also knows the typical acceleration for a car when you slam on the brakes is -4 m/s2. The speed limit for this area is 100 km/hr (about 28 m/s). Was the car speeding before it hit the brakes?
