Explosions in One Dimension: a 10

question 27

Short Answer

Explosions in one dimension: A 10.0-kg shell is traveling horizontally to the right at 25.0 m/s relative to the ground when it explodes into two fragments, one of mass 3.00 kg and the other of mass 7.00 kg. The lighter fragment goes directly forward, and the explosion releases 1.50 × 10³ J of mechanical energy to the fragments. Find the magnitude and direction of the velocity of the heavier fragment relative to the ground just after the explosion. Ignore the effect of any ejected gases.

Definitions:

Synovial Fluid

A viscous, non-Newtonian fluid found in the cavities of synovial joints, serving as a lubricant to reduce friction between the articular cartilages during movement.

Collagen

A key structural protein found in skin, bones, tendons, and other connective tissues, responsible for providing strength and elasticity.

Joint Capsule

A saclike structure surrounding a joint, providing protection and support, containing synovial fluid which lubricates the joint.

Mucous Membrane

A layer of epithelial tissue that lines various cavities in the body and secretes mucus, which is involved in moisture regulation and protection against infection.
