A car is driven 225 km west and then 98 km southwest (45°). What is the displacement of the car from the point of origin (magnitude and direction)?

Explanation:

Given

First car travels west so its position vector is given by

then it travels in south-west direction for

so position vector of is

Magnitude of displacement is given by

uranium fissions/breaks up giving out energy and neutrons

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.
