Question

i would like help to write a program to run the following application in visual studio C++, CLR empty project

Borough of Manhatan Community College The City University of New York SCIENCE DEPARTMENT Laboratory Experiment ACCELERATION DUE TO GRAVITY USING A SIMPLE PENDULUM To calculate the value of the acceleration due to gravity by measuring the period of a pendulum with four different lengths. Apparatus Drilled steel ball, string, clamp, support to hold pendulum apparatus, meter stick, and timer Theory: An object, which is allowed to fall freely near the Earth's surface, accelerates downward by the attractive gravitational force exerted by the Earth. The time it takes a simple pendulum to make a complete swing (back and forth) is called its period (T). If the pendulum is allowed to swing through a small angle, the period is given by the equation 9-98 0 where L is the length of the pendulum measured from the point of suspension of the string to the center of the pendulum bob. The acceleration due to the gravity of Earth is g, and t is the constant, called pi, which is approximately equal to the value 3.14 Rearanging the above equation, we can use T' ploted apainstL cl 0.ss 0.4S Suspend a steel ball from the stand by a string. Adjust the distance from the point of suspension to the center of the ball to be 30 cm (centimeters), which is equal to 0.3 m (meters). This is the value of L 1. 2. Displace the ball from resting by a small amount, about 20 cm, and allow the ball to swing freely Measure the time in seconds for 15 complete swings (back and forth). Record the value in the second column of your data page. In the third column of your data page, take that time and divide by 15 to find the period of one complete swing of the pendulum (T) in seconds 3. 4. Repeat steps (1) to (3), changing the leagth of the pendulum to 55 cm 5. Repeat steps (1) to (3), changing the length of the pendulum to 75 cm 6. Repeat steps (1) to (3), changing the length of the pendalum to 100 cm 31 7. Plot the graph of T against L drawing the best fit straight line through the points ona separate sheet of graph paper Calculations and Questions: 1. Calculate the value of the acceleration due to gravity (g), by selecting a new data point orn the best-fit curve to use to calculate value of the slope of the line in your graph. Compare your result with the accepted value, which is g-98 2. Does the period, T, change when you change the length of the string, L.? If so, how so? 3. What is acceleration in your own words? What is g in your own words?
