Question
I am having trouble calculating some values for an experiment in which I set up a ramp at different angles to measure time a ball took to reach certain points (e.g. 10 cm. 40 cm. 60 cm. 90 cm, and 160 cm from the starting point). Here are the angles I used and their timing: Angle Time (10 cm) Time (40 cm) Time (60 cm) Time (90 cm) Time (160 cm) 6.03 0.58 s 1.4 s 1.52 s 1.83 s 2.49 s 7.85 0.55 s 1.21 s 1.37 s 1.49 s 2.14 s 10.1 0.44 s 0.87 s 1.14 s 1.26 s 1.71 s 13.25 0.43 s 0.81 s 0.93 s 1.11 s 1.49 s There are a lot of questions, but each one depends on the next, so if you could answer each part that would REALLY help! a) What is the relationship between time, distance and velocity for a given run? b) What are the best fit quadratic regressions for each set of data? c) Calculate the velocity of the angles 6.03 and 13.25 in these intervals for each angle: 10-40 cm 40-60 cm 60-90 cm 90-160 cm d) Find the best fit linear equation for each of the 2 angles (6.03 and 13.25). e) Next, with these two angles, calculate the acceleration of these 2 angles in these intervals: 0-40 cm 40-60 cm 60-90 cm 90-160 cm Also find the best fit linear equation for each change in velocity vs. time. f) How does changing the angle of the incline change the acceleration-time graph? g) Find the best fit quadratic regression equation for a graph of acceleration vs. sine(angle) for each of the angles. g) Write the general form for a linear (A = gsin(theta) (I think this might be it) equation for projectile motion. Explain the relationship of each coefficient. Find the experimental value of the acceleration of gravity! (Most important part)Explanation / Answer
A. The time will be large for large distane and velocity is the ratio of distance ant time.... so it will be larger if difference in ditance and time is high.. c. vel can be calculated by taking ratio og distances and time e. acc can be gained by dividing vel with time f. graph will show the steight line going upward g. a=a` * sin theta a` is the Horizontal distance exp value of g is = 981 cm/sec^2
