Two planets are on a collision course, heading directly toward each other at 0.250c. A spaceship sent from one planet approaches the second at 0.750c as seen by the second planet. What is the velocity of the ship relative to the first planet? (Explicitly show on paper how you follow the steps in the Problem-Solving Strategy for relativity, found on page 708 of the textbook. Your instructor may ask you to turn in this work.)
A king orders a gold crown having a mass of 0.68 kg. When it arrives from the metalsmith, the volume of the crown is found to be 145 cm^3
A 2.1-kg block is released from rest and allowed to slide down a frictionless surface and into a spring. The far end of the spring is attached to a wall, as shown. The initial height of the block is 0.36 m above the lowest part of the slide and the s..
Two equally charged insulating balls each weigh 0.14 g and hang from a common point by identical threads 30 cm long. The balls repel each other so that the separation between their centers is 6.4 cm. What is the magnitude of the charge on each bal..
