Title: How does a moving cart rolling down a slope? Objectives: Adapt the traditional vertical and horizontal axes to a coordinate system aligned with a slope. Determine the acceleration of a cart that rolling down from a frictionless track (our assumption) by calculating theoretically and measuring experimentally. Compare the experimental and expected values of acceleration. Show that the acceleration of a cart moving down a slope (from frictionless track) is dependent on the angle of the slope

1 Introduction ANSWERS TO MULTIPLE CHOICE QUESTIONS 1. Using a calculator to multiply the length by the width gives a raw answer of 6783 m 2 ‚ but this answer must be rounded to contain the same number of significant figures as the least accurate factor in the product. The least accurate factor is the length‚ which contains either 2 or 3 significant figures‚ depending on whether the trailing zero is significant or is being used only to locate the decimal point. Assuming the length contains 3 significant

between radiuses‚ mass‚ velocity and centripetal force of a spinning body. We used logger pro to accurately measure the orbital period of the spinning mass and used these measurements to determine the interrelated interactions of the specified properties and viewed the results graphically. Data and Calculations The black markings on the string are about 10 cm apart in length‚ measured from the center of the spinning mass. Part A: Factors that influence Circular Motion Velocity versuse Centripetal

The purpose of this experiment is to find out the relationship between the spacing of the magnets in a Gauss Rifle and the velocity of the last ball‚ and use it to determine the maximum velocity that can be achieved. III. Significance of the Study It is important for us to know whether the spacing in-between magnets would affect the overall velocity of the last ball. This will give us accurate measurements to improve the speed of the ball.

Additional Questions 3: Kinematics 1. A balloon is 30.0 m above the ground and is rising vertically with a uniform speed when a coin is dropped from it. If the coin reaches the ground in 4.00 s‚ what is the speed of the balloon? Solution:- Initial velocity of coin = speed of balloon‚ v. by using the equation [Answer: 12.1 ms–1] 2. A car and train moves together along two parallel paths at 25.0 ms–1. The car then undergoes a uniform

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. The vectors appear to have both direct and inverse relationships with each other. When I move the ball one direction‚ both of the vectors move the

edges the acoustic flow velocity amplitude is comparable to the main flow velocity. A two-dimensional potential flow model based on the vortex blob method‚ used to simulate the flow in the junction‚ describes accurately the flow visualization and laser Doppler data obtained in pipes with square cross-sections and with sharp edged junctions. The numerical simulation is used to calculate the acoustical power generated by the vortical flow at a given amplitude of the acoustic velocity field and Strouhal number
