A Shell Is Launched from a Cannon and Explodes Mid-Air

question 29

Multiple Choice

A shell is launched from a cannon and explodes mid-air.Which of the following is correct after the explosion?

• A)Since the explosion exerts external forces on the shell, neither its horizontal momentum nor its vertical momentum is conserved.
• B)Since the explosion exerts only internal forces on the shell, both its horizontal and vertical momenta are conserved.
• C)Since the explosion exerts only internal forces on the shell, but gravity is an external force, neither its horizontal momentum nor its vertical momentum is conserved.
• D)Since the explosion exerts only internal forces on the shell, but gravity is an external force, its horizontal momentum is conserved but its vertical momentum is not conserved.
• E)Since the explosion exerts only internal forces on the shell, but gravity is an external force, its vertical momentum is conserved but its horizontal momentum is not conserved.
