You have exactly 6 minutes 30 seconds to get to your next class on time and that classroom is 134 m east of where you are right now. First you run to your dorm room at an average velocity of 4.88 m/s to the south to pick up your calculator and your dorm room is 322 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time?     0.89 m/s     4.88 m/s     1.08 m/s     1.17 m/s

3. The graph below shows the displacement vs time of a student leaving the NSCI 110 after physics class walking towards the cafeteria for lunch (assume a 1-D motion) At some point between NSCI 110 and the cafeteria, the student realizes they have left their cell phone in the classroom, so they turn back to get it. Displacement vs Time 120 100 nol Velocity vs Time 80 1.5 60 40 30 60 90 120 150 180 210 20 -1.5 30 60 90 120 150 180 210 Time (s) a. How far did the student walk before realizing that they left their cell phone in the classroom? How long did this take? (2 marks) b. With what velocity did the student walk back to the classroom? (2 marks) c. Fill out the velocity vs time graph above. (2 marks) Distance (m)

You have exactly 5 minutes 20 seconds to get to your next class on time and that classroom is 303 m east of where you are right now. First you run to your dorm room at an average velocity of 4.54 m/s to the south to pick up your calculator and your dorm room is 220 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time?

NASA launches a rocket at t = is given by h(t) = - 4.912 + 349t + 318. O seconds. Its height, in meters above sea-level, as a function of time Assuming that the rocket will splash down into the ocean, at what time does splashdown occur? The rocket splashes down after seconds. How high above sea-level does the rocket get at its peak? The rocket peaks at meters above sea-level.

Can I please get some help with this problem. I can't seem to figure this out. thank you!

You have exactly 3 minutes 20 seconds to get to your next class on time and that classroom is 472 m east of where you are right now. First you run to your dorm room at an average velocity of 5.34 m/s to the south to pick up your calculator and your dorm room is 350 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time?

You have exactly four minutes 29 seconds to get to your next class on time and the classroom is 166 m east of where you are right now. First you run to your dorm room at an average velocity of 4.39 m/s to the south to pick up your calculator and your dorm room is to 16 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time?

A rhinoceros is at the origin of coordinates at time t1 = 0. For the time interval from t1 to t2 = 11.0 s, the rhino's average velocity has x-component - 4.20 m/s and y-component 5.10 m/s.  a. At time t2 = 11.0 s what is the x-coordinate of the rhino? b. At time t2 = 11.0 s what is the y-coordinate of the rhino? c. How far is the rhino from the origin?
