A 0.149 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/s . It has a head-on collision with a 0.301 kg glider that is moving to the left with a speed of 2.18 m/s . Suppose the collision is elastic.
Part A:
Find the magnitude of the final velocity of the 0.301 kg glider.

Solutions

Expert Solution

Given:

Mass of 1st glider,

speed of 1st glider,

Mass of 2nd glider,

speed of 2nd glider, (Negative sign indicates left direction)

------------

Find the magnitude of the final velocity of the 0.301 kg glider.

During collision momentum is conserved

Initial Momentum = Final Momentum

---------------------------(1)

==========================

Given that the collision is elastic

So kinetic energy is conserved

initial kinetic energy = final kinetic energy

Put (1) in above equation

Multiply all terms with 0.149

Solve the quadratic equation with a calculator
