PHY 101 Introductory Physics Test 3 Study Questions Well Answered Latest Update A 20-g bullet is fired into a 2.0-kg block of wood placed on a horizontal surface. The bullet stops in the block. The impact moves the block (+ bullet) a distance of 5 m before it comes to rest. If the coefficient of kinetic friction between the block and surface is 0.25, calculate the speed of the bullet immediately before the impact. - Answers 500 m/s Two asteroids are drifting in space with trajectories shown i...

PHY 101 Midterm Exam Questions Answered Correctly Latest Update How did Aristotle describe the state of motion of the Earth - AnswersEarth has natural motion downward toward the center What was Galileo's understanding of friction - AnswersWhen there was less friction, the motion of objects persisted for a longer time; the less the friction, the more the motion approached constant speed. He reasoned that, in the absence of friction or other opposing forces, a horizontally moving object woul...

PHY 101 CHAPTER 1 TEST QUESTIONS AND ANSWERS FULLY SOLVED LATEST UPDATE Professor Boredom has noticed that his students keep falling asleep during his lectures. He thinks that keeping the lights in the lecture hall on at their brightest level will help to keep students awake. He decides to give the same lecture to three groups of people. He holds one class session with bright lights, one class session with normal lighting, and one class session with dim lights. Professor Boredom has a teaching...

average speed = distance/time average velocity = displacement / time slope of position vs time graph = average velocity speeding up velocity and acceleration have the same sign slowing down velocity and acceleration have opposite signs slope of velocity vs time graph = acceleration acceleration due to gravity = 9.8 area blow a velocity vs time graph = displacement

Which of the following is a scientific hypothesis?the moon is made of green cheese To be dimensionally consistent, velocity, acceleration and time must be related as follows:velocity = acceleration x time By what factor does the volume of a cube increase if the length of all the edges are tripled?27 1 angstrom =10^5 fermi On a graph of x versus time, the slope representsthe x part of the velocity, vx When a rock is thrown straight upwards, at the exact top of its path, itsvelocity is ze...
