Exercises for Chapter 1 Kinematics 1. An impulsive retarding force of 3 seconds duration acts on a particle which is moving with a forward velocity of 60 m/s. The oscilloscope record of the deceleration is shown. Determine the approximate velocity of the particle at t = 9 s. [answer: -58 m/s] 2. A car can decelerate at 0.8 ‘g’ on a certain road.

Mass Affecting Final Velocity Name: Anlin Pereira Class: 11C The lab was conducted on 24th September 2014 Teacher: Ms. Timlin Research question: How does the mass (grams) affect the final velocity (m/s) of the toy car on a one meter ramp? Aim: To carry out an investigation to prove that factors such as mass (grams) affects the final velocity (m/s) of an object as it travels a straight line and has a constant acceleration (m/s²). Hypothesis: It is predicted that the mass of the moving object

Human interdependence‚ the value of emotion‚ moral obligations in particular relationships‚ private and public traditions‚ and relationships are several of Held’s criteria for something to be the highest good. I believe all of Held’s following criteria are necessary for someone to reach the highest good. Held believes that in order for something to be the highest good‚ it must be based on a moral realistic

motion of objects without considering the effects that produce the motion. This experiment will show how to determine the linear motion with constant (uniform) velocity particularly the dynamic cart and linear motion with constant (uniform) acceleration‚ (e.g. free fall of motion). At the end of the experiment we found out that the velocity is a speed that involves direction of an object as well as the time. While for the acceleration‚ it is directly proportional to the distance or height but inversely

Introduction: This lab is an experiment in terminal velocity‚ the speed an object cannot surpass due to frictional forces. To begin‚ it is important to note that the objects in this lab are not in a free-fall scenario. A free-fall scenario is a situation where an object is dropped in a frictionless environment‚ and the only force that is acting upon it is the force of gravity. In a free fall environment‚ terminal velocity would not occur‚ because no frictional forces would act on the object to
