Question1

A 4.7-g object moving to the right at 38 cm/s makes a flexible head-on collision with a 9.4-g object that is initially at rest.

What is velocity of the 4.7-g mass after the collision?

What fraction of the initial kinetic energy was transferred to the 9.4-g block?

Question2

A loudspeaker of mass 17.0 is suspended a distance of = 1.60 below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of = 3.50. What is tension in each of the cables?

Use 9.80 for magnitude of the acceleration due to gravity.
