radius is 48 degrees; how to calculate #3? t= 1.76sec; how to calculate #4?

Activity: 1. When the pig is ying in a consistent circle, measure the radius of the circle, r 2. Determine the angle that the string makes from vertical, 6. 3. Calculate the theoretical velocity, using the equation you developed in step 7 of the pre-lab with the measured values for r and 6. 4. Measure the speed of the pig. To do this, measure the time it takes to complete 10 revolutions, and divide by '10 to nd the time for a single revolution, t. The linear distance covered in that time is the circumference of the circle, 2m. Velocity is found by dividing the distance by the time to cover that distance. 27a?\" v = t 5. Compare the two velocity values. Suggest sources of error
