The other day, while riding my bike, I was forced to stop quickly to avoid a squirrel in the middle of the road 60 feet ahead. I decelerated at a constant rate of 15 ft/sec², skidding all the way. One second into the slide, my trip computer said I was going 27 ft/sec. How far did I skid before stopping? Did I avoid hitting the squirrel? Round to the nearest tenth

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day and he is blown along the following directions: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 1.30 km and 25.0 south of west, then 5.10 km straight east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use a graphical method to find the castaway’s final position relative to the island.
You hopefully used g=9.8 m/s2 (or thereabouts). That is the gravitational acceleration near the earth's surface. if you rise high above the earth, the gravitational acceleration decreases. Specifically, the gravitational acceleration is inversely proportional to the square of the distance from the earth's center. Equivalently, if you multiply the acceleration by the distance from the earth's center, you should get the same number for all heights. For this problem, take the radius of the earth as 3,902 miles, and calculate the gravitational acceleration of a satellite in low orbit, 182 miles above the surface.
When I did p 2.37 I got zero but that is not the correct answer. I need help.
In my assignment, I was asked to perform a lab experiment. I was to take a provided ball and roll it at a given angle at measured increments - 0.1m-.8m. I measured the time in seconds it took to go from 0 to each point - 0-.1, 0-.2, etc. My lab assignment asked me to perform each step three times. I did this, rolling the ball 3 times from 0-0.1 and calculating the time. I used an app on my phone, slowed down, and went to the closest time interval I could for each test. Naturally, my results for each of the 3 tests for all 8 distances was a bit off, as I would expect given my inexperience and inaccuracy of the tools used to begin with. The lab then asks to chart these values - which I inserted a chart of each trial, the time of each trial, and then calculated the average time ((trial 1 + trial 2 + trial 3)/3). The part I am stuck on is that the next activity it asks me for is: "Calculate the square of the average time for each distance, then create a graph of displacement vs. time…

Which of the following quantities are vectors, and which are scalars? Be sure to explain the reasoning for your answer.(a) A bird flies a distance of 20 m.(b) A train is travelling at 100 km/h due north.(c) It takes an athlete 10.37 s to run 100 m.
The formula v = v2.3r models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvature r, in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 470 feet. What is the maximum safe speed? For this problem, round your answer DOWN to the nearest whole number. (Think: Why is this type of rounding appropriate for this scenario?) max safe speed =
Amel goes for a walk with a speed of 3kph. After 30 minutes of walk, his wife follows him. Walking 3.25 km for the first hour, 3.75 km for the second hour, 4 km for the third hour and so on maintaining a speed of .25 km per hour. How many hours does the wife take to catch up to her husband?

An astronaut is rotated in a horizontal centrifuge at a radius of 5.6 m. How many revolutions per minute are required to produce if the centripetal acceleration has a magnitude of 5.3g? ( g is the gravitational acceleration, g=9.80 m/s2. Your result must include one digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take π=3.14)
1d. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) x= y=
Two cars X and Y race around a 1,320 m circular track. With the same starting point and traveling in opposite directions, they meet for the first time after 2 minutes. When traveling at the same direction and starting at the same point, car X reaches the starting point with car Y 220 m behind. What is the rate of X in kph? С. 21 D. 24 A. 15 В. 18
