Let m1 and m2 be the two masses, whereby m1 is the one that stops upon collision (assuming an elastic collision). We use the conservation of the momentum for this situation, namely the total momentum of the two moving masses is conserved and equal the momentum of the mass2 after the collision:
From this we can determine the resulting velocity:
Which answers the question for general values of m1, m2, v1, and v2.
For instance, if m1=m2, and v1=v2=1 m/s then the resulting velocity of the mass2 would be sqrt(2) m/s in the direction of 45 degrees from its original path.
When atoms that are shaking with kinetic energy collide with the dust particles, it causes the dust particles to move with the Brownian motion.
Hope this helps ;)
Answer:
Option B
Explanation:
Weight can be measured in pounds. Pounds is a unit of weight.
=> Mass is measured in kgs
=> A bowling ball has more mass than a golf ball.
=> Objects do not have the same weight regardless of where they are. The weight depends on where they are as it depends on the acceleration due to gravity (g)
