The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans and animals. When grown in a uniform medium rich in salts and amino acids, these bacteria swim along zig-zag paths at a constant speed of 20 μm/s. The figure shows the trajectory of an E. coli as it moves from point A to point E.

A batter hits a fly ball with an initial velocity of 37 m/s at an angle of 32° from the horizontal. How much time does the outfielder have to get to the appropriate position to catch the ball?
Dylan and Sophia are walking along Bluebird Lake on a perfectly calm day. Dylan, determined to impress Sophia by his ability to skip rocks, picks up the flattest rock he can find and gives it a sidearm launch from the edge of the water. The rock acquires a completely horizontal speed of 27.2 m/s from a height of 0.54 meters above the water surface. How much time does it take to hit the surface of the water?

A cannon ball is fired with an initial speed of 123 m/s at an angle of 60 degrees from the horizontal.Express the initial velocity as a linear combination of its unit vector components.Find the maximum height reached by the cannon ball and the time needed to reach the maximum height.Find the speed of the cannon ball at the maximum height and the magnitude of its acceleration.
I asked the question here before but the solution was wrong. that's why I will ask again. Sam and William are playing with a ball. Sam throws the ball 30 s after William started to run away from the starting position. If William is accelerating 1.6 m/s2 starting from rest, find the initial velocity of the ball to hit the moving target and the ground at the same time. The ball is thrown 1.5 m from the ground and 46° from the horizontal. Choices: a. 112 m/s b. 126 m/s c. 163 m/s d. 143 m/s
A man runs around a circular track of 800 meters radius for 30 seconds, starting at a point directly to the right of the center and goes in a counterclockwise manner. He goes 5 meters per second for the first 15 seconds, runs 90 meters for the next 6 seconds and then 180 meters for the rest of the course. What was his average speed, his displacement from the starting point, his average velocity, and his total displacement upon return to the starting point?
An airplane undergoes the following displacements: First, it flies 66 km in a direction 30° east of north. Next, it flies 49 km due south. Finally, it flies 100 km 30° north of west. Using vector components, determine how far the airplane ends up from its starting point. A test rocket is fired straight up from rest with a net acceleration of 20.0 m/s2 upwards. After 4.00 seconds the motor turns off, but the rocket continues to coast upward with no appreciable air resistance (deaccelerating). What maximum elevation does the rocket reach during its flight H DELL O W
Having trouble figuring this one out: A playful cat sees a mouse run past him with a constant velocity of 2 m/s. One second after the mouse passes the cat, the cat jumps after the mouse at an angle of 30 degrees and some unknown initial velocity. Being a naturally-talented cat, he lands perfectly right where the mouse ends up (the mouse didn't think to turn or change his speed). What is the initial velocity of the cat?
You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 50° from the edge of the building with an initial velocity of 10 m/s and lands 20 meters away from the wall of the building. Which equation will allow you to solve for the amount of time the ball is in the air? Hint: look at your givens in the x-direction. Group of answer choices A. vfx2=v0x2+2axΔx B. vfx=v0x+axt C.

A fly ball is hit to the outfield during a baseball game. Let’s neglect the effects of air resistance on the ball. The motion of the ball is animated in the simulation (linked below). The animation assumes that the ball’s initial location on the y axis is y0 = 1 m, and the ball's initial velocity has components v0x = 20 m/s and v0y = 20 m/s. What is the initial angle (in degrees) of the baseball's velocity? (Write only the numerical value of the answer and exclude the unit) Blank 1
A spacecraft has an initial speed of 3037 m/s at an angle of 27 degrees above the positive x axis. Two engines fire for 5.4 seconds, and produce an acceleration of 9.9 m/s/s at an angle of 18.5 degrees above the positive x axis. What is the final speed of the spacecraft? What angle is it at above the positive x-axis?
