1). A stone is dropped from rest from the top of a tall building‚ as Figure 2.17 indicates. After 3.00 s of free-fall‚ what is the displacement y of the stone? | The stone‚ starting with zero velocity at the top of the building‚ is accelerated downward by gravity. | | Reasoning The upward direction is chosen as the positive direction. The initial velocity v0 of the stone is zero‚ because the stone is dropped from rest. The acceleration due to gravity is negative‚ since it points downward

A STRAIGHT LINE GUIDE QUESTIONS: 1. From the data obtained‚ what is the effect of the height of the track to the cart’s acceleration? The data shows that sinӨ‚ which is dependent on the height‚ is getting higher as acceleration is increasing. This implicates that when object is at higher altitude‚ its acceleration is faster. 2. From the data obtained‚ how is time‚ t related to the inclination of the track? Explain why? Time and position of velocity are interrelated to each other and the

Lab #3: Initial Velocity of a Projectile | | | Abhishek Samdaria | Pd.4 and 5 | | Lab #3: Initial Velocity of a Projectile Theory: How can we determine the initial velocity of a projectile? Experimental Design: The purpose behind this experiment was to determine the initial velocity of a projectile. Projection motion consists of kinematics of motion in the x and y directions. With two dimension kinematics‚ there are the x and y components in any given velocity. In projectile

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.

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 proportional to the time. By close observations

an essay on the following topic: "Discuss cultural differences as they exist in American and Vietnamese culture and suggest some ways to overcome them." CONTENT The difference of culture impacts so much to the way to living‚ the way of thinking and the way of doing business. America and Vietnam have a big difference in culture‚ religion and business. However‚ we live in a world where it is called flat world‚ where there is no restriction between countries. It requires us to integrate in order to

Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividing it over the time. The equation is: a= ∆v∆t (“Acceleration”) Acceleration is also a vector because it has a direction. The units of acceleration are typically m/s2. Gravity is the force that attracts
