25. An ice skater glides across the surface of a frozen lake. At a certain moment its displacement is defined by the vector displacement: D= (20 meters)i + (+8.50 meters) j If 30 seconds later the skater comes to an instant stop, determine: ● What is the magnitude of the velocity that it carries during this interval? What is its direction of the resultant velocity vector with respect to the original path? Select one: a. Magnitude of the velocity is -0.27 meters/second and the direction of the vector is 20 degrees b. Magnitude of the velocity is 0.90 meters/second and the direction of the vector is 22.7 degrees c. Magnitude of the velocity is 0.72 meters/second and the direction of the vector is 22.7 degrees d. Magnitude of the velocity is 0.72 meters/second and the direction of the vector is 29.7 degrees

3. The position of an object as a function of time is r(t) = (7t³ - t)i + (3t²)ĵ. Find the magnitude and direction of the object's displacement vector AF as a function of time relative to the initial position (at which t = 0) at t = 7.
Geese migrate along north and south directions for well over a thousand kilometers in some cases traveling speeds up to about 100 km/h. If one such bird is flying at 100km/h relative to the air but there is a 34.0 km/h wind blowing from the west to east. A.) at what angle relative to the north-south direction should this bird head so that it will be traveling directly southward relative to the ground? Express answer in degrees b.) how long will it take the bird to cover a ground distance of 500 km from north to south? ( Note: Even on cloudy nights many birds navigate using the earth's magnetic field to fix the north-south direction)

Here you are designing a motorcycle stunt where the motorcycle leaves a ramp at an angle θ and lands on another ramp of the same height. You need to know where to place the second ramp. You will make a mathema1cal model to predict the range (i.e., to predict how far the motorcycle will land from the first ramp).

S21: A hicker begins a trip by first walking 30 km southeast from her car. She stops and sets up her tent for the night. On the second day, she walks 25 km in a direction 60 north of east, at which point she discovers a forest ranger`s tower. Determine the components of the hicker`s .displacement in the x-axis
Lesson: Projectiles When there is air resistance present how to the velocity and acceleration vectors behave? O The acceleration vector is perpendicular to the trajectory and the velocity vector is at a tangent to it. O The acceleration changes throughout the flight with its x-component opposite the direction of motion. The velocity vector is at a tangent to the trajectory O The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory O The acceleration and velocity vectors are both constant magnitude but continually change direction.
