At time t = 0, two starships set out from their homebase on Earth, which they all agree is at x = 0. Both ships head directly for planet LV-426, which is infested with vicious aliens. According to earth controllers, LV-426 is 3 lightyears away. The starship Flyby travels at a constant speed 0.8 c; its mission is to take photos of the situation on LV-426 as it flies past the planet. The second ship, the Sulacco, travels at a...
(1 point) A stone is thrown from a rooftop at time t 0 seconds. Its position at time t (the components are measured in meters) is given by r()-бі-50+ (24.5-49:2) k. The origin is at the base of the bulding, which is standing on flat ground. Distance is measured in meters. The vector i points east,j points north, and k points up. (a) How high is the rooftop? meters. (b) When does the stone hit the ground? seconds (c) Where...
Interactive Exercises 4.03: Position and Velocity in Two Dimensions (Space Debris) In a far off galaxy, space debris is blasted into very small (and hence harmless) fragments by means of explosive torpedoes that are fired from special guns. An engineer is to program two such guns to destroy a large asteroid in an interplanetary region-where the effects of gravity are negligible. The first gun is at the origin of an ry coordinate system, as shown in the simulation (linked below)....

(c) The molar mass of oxygen atoms is 16.0g mol-1. The oxygen molecule O2 can be considered as two massive points (representing the oxygen atoms) separated by a distance of 1.21 x 10-10 m. The origin of the Cartesian coordinate system is placed in the molccular centre of mass and the a-axis is aligned along...

2. A mass of m kilograms (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixed to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The...

My Notes + Ask Your Teacher John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of a = 20.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 405 N is exerted at the center of the wheel, which has a radius of 15.0 cm....
