Suppose you drive from home to your child’s school, pick her up, and drive back home, covering a total distance of 25 miles in 1 hour. which of the following statements are true? select all the true statements. select all the true statements. your average speed for the trip is zero. you must accelerate when you reach the school. your average velocity for the trip is 25 miles per hour. your average speed for the trip is 25 miles per hour. your velocity is different on the return home than it is on the way to school.

average speed of trip is 25 mph

Explanation:

Given

Total distance is 25 miles (i.e. from home to school and then back to home)

Total time taken = 1 hour

so average speed

average velocity

displacement is zero here

Velocity for return trip is different as compared to way trip as velocity is a vector quantity so it will be different for both trip.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
