A person drops a stone from the window of a building. One second later, she drops another stone. How does the distance between the stones vary with time?
Answer to relevant QuestionsHow would free fall on the Moon differ from that on the Earth? A student runs 30 m east, 40 m north, and 50 m west. (a) The magnitude of the student’s net displacement is (1) between 0 and 20 m, (2) between 20 m and 40 m, (3) between 40 m and 60 m. (b) What is his net displacement? The displacement of an object is given as a function of time by x = 3t2 m. What is the magnitude of the average velocity for (a) ∆t = 2.0 s – 0s, and (b) ∆t = 4.0 s – 2.0s? A couple is traveling by car down a straight high-way at 40 km/h. They see an accident in the distance, so the driver applies the brakes, and in 5.0 s the car uniformly slows down to rest. (a) The direction of the ...Figure 2.24 shows a plot of velocity versus time for an object in linear motion. (a) Compute the acceleration for each phase of motion. (b) Describe how the object moves during the last time segment.
