. Two objects of the same mass move along the same line in opposite directions. The first mass is moving with speed v. The objects collide, stick together, and move with speed 0.100v in the direction of the velocity of the first mass before the collision. 1.How much kinetic energy is lost during the collision?

Two conducting spheres have identical radii. Initially they have charges of opposite sign and unequal magnitudes with the magnitude of the positive charge larger than the magnitude of the negative charge. They attract each other with a force of 0.27 N when separated by 0.4 m. The spheres are suddenly connected by a thin conducting wire, which is then removed. Now the spheres repel each other with a force of 0.045 N. A.) What is the magnitude of the positive...

Two cars are driving at the same constant speed on a straight road, with car 1 in front of car 2. Car 1 suddenly starts to brake with constant acceleration and stops in 10 m. At the instant car 1 comes to a stop, car 2 begins to brake with the same acceleration. It comes to a halt just as it reaches the back of car 1. What was the separation between the cars before they starting braking?

Compare the kinetic energies of two objects, A and B, identical in every respect except one. Assume that the single difference is: Object A has twice the velocity of B. Object A moves north, B south. Object A moves in a circle, B in a straight line. Object A is a projectile falling vertically downward; B is a projectile moving vertically upward at the same speed. Object A consists of two separate pieces attached by a light string, each equal in...

Chapter 19, Problem 28 GO identical point charges of +1.3 μC are fixed to diagonally opposite corners of a square. A third charge is then fixed at the center of the square, such that it causes the potentials at the empty corners to change signs without changing magnitudes. Find the sign and magnitude of the third charge Number Units
