Make 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. What is the total displacement of the jeepney?

According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?
Hi I am in physics 1 and I need help with this problem. It saids a boy runs in an open field. He runs 233m due north in 77 seconds, turns 90 degrees to his left and runs 178m in 93 seconds. Sketch a map of his motion and find the following quantities of his motion during this period from starting time to final time a) Map of his motion b) The total distance he runs (233m + 178m= 411m) c) The displacement from starting position to final position. What I have thus far is I got c=sqrt (233)^2+(178)^2=293m. Would I subtract this number from the total distance? Please includes detailed steps of how to solve this
Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!
Solve for the correct answer and show complete solution w/ illustration. Two people on bikes are separated by 350 meters. Person A starts riding north at a rate of 2m/sec and 7 minutes later Person B starts riding south at 3m/sec. At what rate is the distance separating the two people changing 25 minutes after Person A starts riding? a. 4m/s b. бт/s с. 5m/s d. 7mls
George runs the football 40 yards downfield before he is tackled. The straight line distance between where he began the run and where he was tackled is 18 yards and makes a 25 degree angle with the right sideline. a. What was George's distance traveled in yards? b. What was George's resultant displacement in yards? PIck answer BELOW a. distance = 58yds, displacement = 18yds b. distance = 40yds, displacement = 22yds c. distance = 40 yds, displacement = 18yds d. distance = 18yds, displacement = 40yds

An invented robot can comprehend time through resultant vector once the hour hand and minute hand vectors were added together. Assuming that both vectors point from the center, outward. The length of the hour hand is 5.10 cm while the length of the minute hand is 10.50 cm Follow this given format in answering each sub-item: a. Draw the position of the hour and minute on clock for time configuration. Label with relevant angles and magnitudes b. Decompose the components of each vector along the x and y direction c. Calculate for the resultant vector and express in the form required in each item What would you tell the robot if the current time is: A. 10:30 AM, in bearing form? (FORM: magnitude - direction angle) B. 1:25 PM, in unit vector form? (FORM where Ā = Āx + Ãy = Ax î + Ay§. )

Do not solve the full qn My question is why is the vector VAot = 1.5 and VAon =-2.6 as shown in the solution. I understand VAot is = -3cos30=-1.5 and VAon = -3sin30 =-2.6 Why is it postive 1.5 instead of negative 1.5 or for VAon why isit negative 2.6 and not positive 2.6? Are you able to show in a vector diagram

In a total time of 3.0 minutes, a duck on a pond paddles 31 m [N33oE] and then paddlesanother 57 m [E28oS]. Solve for the displacement graphically (with a ruler andprotractor) and then answer the questions. Using the displacement you determined from your graph, what was the duck’s average velocityfor the trip? What total distance did the duck travel? What was the average speed of the duck for the whole trip?
