- I PRELIMINARY QUESTIONS 1. One of the timing devices Galileo used was his pulse. Drop a rubber ball from a height of about 2 m and try to determine how many pulse beats elapsed before it hits the ground. What was the timing problem that Galileo encountered? 2. Now measure the time it takes for the rubber ball to fall 2 m, using a watch or clock with a second hand or seconds display. Did the results improve substantially? 3. Roll the hard ball down an incline that makes an angle of about 10° with the horizontal. First use your pulse and then your watch or clock to measure the time of descent. 4. Do you think that during Galileo's day it was possible to get useful data for any of these experiments? Why?arrow_forwardThe graph below shows the speed of an object plotted versus time. Each of the increments on the speed axis is 3 m/s. Each of the increments on the time axis is 2 seconds. Again, each graph inflection point cooresponds to tick marks on the axes.

What is the total distance travelled by the object (that is, from point A to F)?arrow_forwardSupply what is asked with the correct integer values, i.e. no decimal places.

- Explain why we only consider one dimensional motion when using a single motion sensor. Based on the definition of velocity, describe what you should observe in the velocity vs. time graph if you were measuring a stationary, distant object and you suddenly slid and object into the beam from the side [hint: think about the behavior of the position graph in this case.]arrow_forwardMake the proper representation for each of the following problems and solve completely. 1. A euglena swims with a speed of 3.5 µm/s, and swim across the ends of the diameter of an 8.0 cm petri dish. Find the time it takes to swim across the ends of the petri dish. 2. A dog runs 100m away from its master in a straight line in 9.0s, and then runs halfway back in one-third the time. Compute a) its average speed and b) its average velocity. 3. A jeepney starts from rest and moves with an acceleration of 0.5 m/s² until it reaches the velocity 5 m/s, runs at this speed for a time, then applies the break to decelerate at 1.0 m/s² until it stops in 30 seconds.

- A car is moving in a positive direction to the right, at the moment we begin to observe it (consider t = 0 sec), the position of the car is 30 m, it has an initial velocity of 20 m / sec and an initial acceleration of - 36m / sec2, it is known that the rate of change of the acceleration is constant and is 18.a) Find the equations for Acceleration, Velocity, and Position. Make your graphs.b) For what instant of time does the speed of the car take its minimum value, and what is that value?c) In the graph of the position, which represents part “b”, is it a minimum, maximum or an inflection point? What is the value of the position for that instant of time? Justify your answer.d) How many times does the car move to the left? Justify your answer.e) At what instant of time is the value of the position 150? - Only subsections "d" and "e" to be resolvedarrow_forwardWrite the actual function that you expect the velocity to obey as a function of time (recall that the initial velocity was 17 m/s). Your function should be a function of time (i.e. the t variable should be left as an independent variable) but all other values should be filled in with numbers. Based on your answer above, what type of curve would you expect the position vs. time function to obey? i.A constant (horizontal) curve? ii.A linear curve? iii.A quadratic (parabolic) curve? iv.Another type of curve, such as cubic, exponential, sine, square root, etc...?
