Physics

A pendulum of length 2.0 m is raised so that it maeks an angleof 43o with the vertical. The mass of the pendulum bobis 1.0 kg. It is released with an initial speed of 1.0 m/s andswings downward. At the bottom of its arc, it collides with the bobof a second pendulum of length 2.0 m and mass 3.0 kg which isinitially at rest. Assume the collision is elastic.

Calculare the speed with which the first pendulum bob strikesthe second.

Determine the speeds of the two masses immediately after thecollision.

Determine the heights that each mass will reach after thecollision.
