Question

Kinematica Lab PHY 231 - University Physics 1 Measurement of acceleration on an inclined plane 1. Incline the track by a few degrees by placing a book or platform jack under one end. 2. Place t hat Place two photogales in gate mode along the track and record the distance between the gates 3 Release the and to Release the cart from the top of the track and record the time it takes the cart to pass through each gate Use these times to compute the average velocity and of the cart at each gate Show work for at least one sample calculation.) i. Hint what displacement should be used? If a new measurement is required, record it in the space below b. Calculate the acceleration of the cart. (Show work for at least one sample calculation) 4. Change the distance between the gates (and record the new distance) and repeat step 3. 5. Repeat step 4 between six and eight times. (A total of between 8 and 10 trials.) 6. Calculate the average value of the acceleration of the cart. 7 In the table and space here, organize and present your data and calculations. Include all relevant info Human Reaction Time 8. Have someone rest their arm on the table with their hand off the edge. Have a different person drop a meter stick through that person's open hand, without warning that person first (don't count down, for example). Record the distance the meter stick falls before the person is able to close their fingers and catch it. 9. Repeat step 8 four times. (A total of 5 trials.) 10. Assume the acceleration of the falling meter stick is 9.8 m/s2. (We'll figure out why in the coming weeks.) Calculate the reaction time for each trial. (Show work for at least one sample calculation.) 11. In the table and space here, organize and present your data and calculations. Include all relevant info.

Answer 1

Q3. You should not observe any variation at all as the acceleration component in the inclined plane comes from the gravity

Q5. Newton's Second law states that f = m.a , so if initial force were given then it must exert some acceleration too.
