Two compressible solids are formed into spheres of the same size. The bulk modulus of sphere two is twice as large as the bulk modulus of sphere one. You now increase the pressure on both spheres by the same amount
As a result of the increased pressure, how is the change in volume of sphere two (?V2 ) related to the change in volume of sphere one (?V1 )? A) ?V2 = 2?V1 B) ?V2 = 4?V1 C) vV2 = ?V1 D) ?V2 = 1/2?V1 E) ?V2 = 1/4?V1

Energy Conservation With Nonconservative Forces: As shown in the figure, a 4.0-kg block is moving at 5.0 m/s along a horizontal frictionless surface toward an ideal spring that is attached to a wall. After the block collides with the spring, the spring is compressed a maximum distance of 0.68 m. What is the speed of the block when the spring is compressed to only one-half of the maximum distance?
