Two gliders on an air track collide in a perfectly elastic collision. Glider A has a mass of 1.1 kg and is initially travelling

Eva8 [605]

m1= mass 1 = 1.1 kg

Vi1 = initial velocity 1 = 2.7 m/s

m2= 2.4 kg

V2i = -1.9 m/s

We assume east as positive and west as negative.

Apply the formulas:

Vf1 = ?

$vf1=(\frac{m1-m2}{m1+m2})Vi1+(\frac{2m2}{m1+m2})Vi2$

Replacing:

$Vf1=\frac{(1.1-2.4)}{(1.1+2.4)}2.7+\frac{(2\times2.4)}{(1.1+2.4)}-1.9$ $Vf1=(\frac{-1.3}{3.5})2.7+(\frac{4.8}{3.5})-1.9$ $Vf1=-1-2.6=-3.6\text{ m/s}$

Answer: 3.6 m/s west

You place a small air cart on a 4.00 m air track and set it into motion with a speed of 0.75 m/s. Due to very good elastic bumpe

san4es73 [151]

Answer:

6 seconds

0.167 Hz

Explanation:

Distance = 4 m

Velocity = 0.75 m/s

Period is given by

$T=2\times Distance\times Velocity\\\Rightarrow T=2\times 4\times 0.75\\\Rightarrow T=6\ s$

The period of the motion is 3 seconds

Frequency is given by

$f=\frac{1}{T}\\\Rightarrow f=\frac{1}{6}\\\Rightarrow f=0.167\ Hz$

The frequency of the motion is 0.33 Hz

What is diffrence between damping and undamping?

ICE Princess25 [194]

Answer:

Oscillation whose amplitude reduce with time are called damped oscillation. This happen because of the friction. In oscillation if its amplitude doesn't change with time then they are called Undamped oscillation
