Two objects with masses m1 = 37 kg and m2 = 39 kg are moving toward each other with speeds V1 = 14 m/s and V2 = 18 m/s. They collide and stick together. Find their final: speed:

Solutions

Expert Solution

Given:

Mass of object 1,

Initial velocity of the object 1,

Mass of object 2,

Initial velocity of the object 2,

Given that the objects are moving towards each other, so if the direction of object 1 is taken as positive then the direction of object 2 should be the opposite.

--------

Given that they collide and stick together.

Let the final velocity be

-------

During collision momentum is conserved

Initial momentum = Final momentum

The negative sign just indicates that after the collision the objects move along the same initial direction as object 2.

Two masses, m1 and m2, are falling but not freely. In addition to gravity, there is also a force F1 applied directly to m1 in the downward direction and a force F2 applied directly to m2 in the horizontal direction. Friction (µs) is present between the two masses and the forces are applied such that they do not rotate. The force F2 is as large as it can be and not have m2 slide relative to m1. (a) Find an...
