Question

A 0.141kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900m/s . It has a head-on collision with a 0.302kg glider that is moving to the left with a speed of 2.25m/s . Suppose the collision is elastic

Find the magnitude of the final velocity of the 0.302kg glider

Answer #1

Let

M_{1}=mass of 0.141 kg glider

M_{2}=mass of 0.302 Kg glider

V_{1i}=Initial Velocity of glider of 0.141 kg ==0.9
m/s

V_{2i}=Iniitial Velocity of glider 0.302 Kg=-2.2 m/s

By conservation of momentum

m_{1}V_{1i}+m_{2}V_{2i}=m_{1}V_{1f}+m_{2}V_{2f}

0.141*0.9-0.302*2.25=0.141V_{1f}+0.302V_{2f}

0.141V_{1f}+0.302V_{2f}=-0.5526

V_{1f}=(1/0.141)[-0.5526-0.302V_{2f}]----------------------1

By Conservation of energy

(1/2)[m_{1}V_{1i}^{2}+m_{2}V_{2i}^{2}]=(1/2)[m_{1}V_{1f}^{2}+m_{2}V_{2f}^{2}]

[0.141*0.9^{2}+0.302*(-2.25)^{2}]=0.141V_{1f}^{2}+0.302V_{2f}^{2}

1.643=0.141*(1/0.141)^{2}[-0.5526-0.302V_{2f}]^{2}+0.302V_{2f}^{2}

1.643=(1/0.141)(0.3054+0.3338V_{2f}+0.0912V_{2f}^{2})+0.302V_{2f}^{2}

1.643=2.1657+2.367V_{2f}+0.6468V_{2f}^{2}+0.302V_{2f}^{2}

0.9488V_{2f}^{2}+2.367V_{2f}+0.5227=0

V_{2f}=-0.245 m/s
