10. [-/2.35 Points] DETAILS OSCOLPHYS1 2.3.011. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHE A student drove to the university from her home and noted that the odometer on her car increased by 12.0 km. The trip took 20.0 min. (a) What was her average speed? km/h "b) If the straight-line distance from her home to the university is 10.3 km in a direction 25.0A south of east, what was her average velocity? km/h (25A S of E) (c) She returned home by the same path. The total time to leave home, travel to the university, and return home was 7 h 30 min. What were her average speed and velocity for the entire trip? average speed km/h average velocity km/h Additional Materials Reading 11. [-/2.35 Points] DETAILS OSCOLPHYS1 2.4.016. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHE A cheetah can accelerate from rest to a speed of 24.0 m/s in 6.75 s. What is its acceleration? m/s Additional Materials Reading 12.
