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.

2. Wellington Wildcat is rushing to get to a parade in time to be the grand marshal. He’s standing in theback of a flatbed truck while McFogg the Dog races at 25 m/s towards town. Suddenly, McFogg sees atiny maple leaf in the road 55 m ahead, and, being a proud Canadian, slams on the brakes to protect thesacred totem. Since McFogg is known to ride the brakes like a real jerk, let’s assume his reaction time tohit the breaks is essentially zero.A. Can McFogg actually stop before the truck reaches the leaf? The coefficients of friction betweenrubber tires and dry concrete are: μs = 1.00, μk = 0.80. When answering this question, be sure toinclude a free-body diagram representing the truck and its stellar mascots as a single object.B. Now here’s the real serious question: Is it possible for McFogg to stop short of the leaf such thatWellington does not slip and slide into the back of the truck cab? The coefficients of friction forWellington’s shoes on the bed of the truck are: μs = 0.60, μk…
You are driving at a constant speed of 45.0 m/s when you pass a trooper on a motorcycle hidden behind a billboard. One second after your car passes the billboard, the trooper sets out from the billboard to catch you, accelerating at a constant rate of 3.00 m/s2. How long does it take the trooper to overtake your car?
