If it takes Ashley 3 seconds to run from the batters box to first base at an average speed (velocity) of 6.5 meters per second‚ what is the distance she covers in that time? 3. Bart ran 5000 meters from the cops and an average speed (velocity) of 6 meters/second before he got caught. How long did he run

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

with constant velocity. 3. The spring was extended to 3cm under mass of 500g. Determine the spring constant. 4. The distance between two planets of masses 25x1025kg and 30x1025kg is 1012km. Calculate the attractive force between them. 5. The load with mass m=1.5kg is attached to the string of length l=1.5m and moves along a vertical circle with constant velocity v=1.5m/s. What are the maximum and minimum tensions in the string and in what positions? Determine the angular speed‚ period and

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 height and gravitational pull affects the acceleration of a moving and a free falling object. 3. From the data obtained‚ how would you account the difference between the picket fence’s acceleration and the value of g? The value of the slope of a graph of average velocity versus time will be the acceleration due to gravity of the falling object.

Acceleration Worksheet 3 Worked Example A cheetah running at 20 m s−1 slows down as it approaches a stream. Within 3.0s‚ its speed has reduced to 2 m s−1. Calculate the average acceleration of the cheetah. Solve the following: 1. A sports car‚ accelerating from rest‚ was timed over 400 m and was found to reach a speed of 120 km h−1 in 18.0 s. a. What was the average speed of the car in m s−1? b. Calculate the average acceleration of the car in km h−1 s−1. c. What was its average

Laboratory – Terminal Velocity Introduction: Consider dropping a piece paper and a brick from the same height. Although in theory they should both strike the ground at the same time; in practice the brick will always strike the ground first. The reason is because of air resistance. As the paper falls to the ground air resistance is pushing the paper up‚ this slows the acceleration of the paper. It is known that as the velocity of an object increases the air resistance acting on the object

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability

Electromagnet even stronger?! To make the magnetic field even stronger‚ you need to apply more current to the circuit. SPEED! Speed is the velocity the object is travelling at. It can be measured by KM/H‚ MP/H‚ MP/S etc. It’s basically how far the object travels in a certain time. The equation for speed is: Speed=Distance÷Time. Distance=Speedxtime. Time=Distance÷Speed. ‘The space shuttle will travel the first 50‚000km of its journey in 2 hours. It will complete the second stage of its journey

Hoàng Hồng Thủy – LQT40A THE DIFFERENCES BETWEEN BRITISH ENGLISH AND AMERICAN ENGLISH INTRODUCTION Those people who complain about the difficulties of learning German‚ don’t know how lucky they really are - they only have one language to master. Admittedly‚ there are regional differences of dialect in German-speaking countries‚ but the non-native speaker who has learned Hochdeutsch (high or standard German) should have no problems in making himself understood by citizens of Germany‚ Austria or Switzerland
