An experimenter is trying to determine the average speed of an object falling to the ground from a height of 2 m, starting from rest. To determine the height, a meter-stick is used (uncertainty: ± 2 cm). To determine the time, a camera is used. The camera records 20 frames per second, so its uncertainty is 0.05 s. The experimenter finds that it took 0.63 seconds for the object to fall. Determine the minimum and maximum values for time, distance and average speed. Show your calculations below, and enter your results in the provided table.

An experiment is performed in an ideal condition to find out the velocity of a particle obeying the equation S=vtS=vt where the distance travelled (S)(S) inside a labeled glass tube by a particle with an uniform velocity (v)(v) is measured with respect to time taken (t)(t). The data collected by repeating the experiment five times is shown in the table below If we use the method to minimize the squared sum error, what is the most likely velocity of the particle among the given options? 2.5 1.5 2 1

Part C: Your friend keeps track of his gas mileage and finds that on average his car uses 20.79488098 miles per gallon (mpg). He has a 15 gallon tank and confidently tells you his vehicle will be able to travel exactly 311.9232147 miles on a single full tank of gas. Explain why you think such a level of precision is absurd.
A snake crawls from a hole to find food. It starts at 8 m SW; then goes 10 m 40o N of W; then sensed something moving 9 mS from where it is and moves to it.b. How far and in what direction was the moving object from the hole?c. If after realizing that the moving object was not good for food, the snake moved from itbecause it saw another moving thing, moved to its direction by covering a fourth unknowndisplacement and is now 20 m and 30o E of S from the hole. Determine the magnitude anddirection of the fourth displacement?
Suppose that the length of an object is measured multiple times. Assuming that random errors are the only source of error, a. Does increasing the number of measurements change the standard deviation for the set? Explain
Part (A). You are designing the radar system to track the UFOs appearing in the city.In your setup, you have two radars R1 and R2, that are 20 miles from each other. And this happens! Oneday the radars detect a UFO somewhere between them. According to the data provided, the angle ofelevation measured by R1 is 35 degrees. The angle of elevation measured by R2 is 15 degrees. What isthe elevation of the UFO? Round your answer to the nearest thousandth mile. Part (B). Now, one of your radar stations is broken. So you have only one radar. The workingradar suddenly detects another UFO. According to the data provided, the angle of elevation of the UFOfrom some point A on the ground is 60 degrees.After flying 15 seconds horizontally, the angle of elevationchanges to 30 degrees.Also, it is detected by your working radar that the UFO is flying at a speed of 200 m/s,can you find the elevation (height) at which the UFO is flying?Round your answer to the nearest thousandth meter.

Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 µs. They are produced when cosmic rays bombard the upper atmosphere about 10 km above the earth’s surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth’s surface. (a) What is the greatest distance a muon could travel during its 2.2 µs lifetime? (b) According to your answer in part (a), it would seem that muons could never make it to the ground. But the 2.2 µs lifetime is measured in the frame of the muon, and muons are moving very fast. At a speed of 0.999c, what is the mean lifetime of a muon as measured by an observer at rest on the earth? How far would the muon travel in this time? Does this result explain why we find muons in cosmic rays? (c) From the point of view of the muon, it still lives for only 2.2 µs, so how does it make it to the ground? What is the thickness of the 10 km of atmosphere through which the muon…
