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 spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384000 km. Suppose it accelerates at an acceleration 20.0 m/s2 for the first time interval 15 min of the trip, then travels at constant speed until the last time interval 15 min , when it accelerates at 20.0 m/s2 , just coming to rest as it reaches the moon. What is the maximum speed attained? What fraction of the total distance is traveled at constant speed? What total time is required for the trip?
Jane is driving down the road at 20.0 m/s looking for a house address. when she sees the house, she slams on her brakes. If her reaction time is 1.20s and her car deaccelerates at 3.50 m/s^2, how far past the point where she first saw the house did her car come to rest? I feel like I need to use one of the 4 kinematics equations, but none seem to be giving me the correct answer when I plug in my numbers :(
Miles wants to chase a truck that is going at a speed of 25.0 kph, and thus starts accelerating from rest at 4.00 m/s. Caesar, sensing that Miles wants to steal property, and seeing him when he is 100.0 m away from him, rides a police car and starts accelerating at 10.0 m/s. Once Caesar’s car catches Miles, what is the distance traveled by the truck since Caesar started chasing Miles?
