Answer:
bird's speed = 4.58 m/s
Explanation:
given data
mass of bird mb = 300 g
velocity of bird vb = 5.7 m/s
mass of insect mi = 10 g
velocity of insect vi = - 29 m/s
solution
here momentum of system is constant
we apply here conservation of momentum so
mb × v + mi × v = mb × vb + mi × vi ....................1
v ( mb + mi ) = mb × vb + mi × vi
put here value and we get
v ( 300 + 10 ) = { 300 × 5.7 } + { 10 × (-29) }
v =
v = 4.58 m/s
Answer:
Explained
Explanation:
Newton would resort to the classical mechanics and say that the momentum of the particle that is moving with a constant velocity will be given by: momentum = mass x velocity
this approach will highlight the particle nature and will not be relativistic.
De-Broglie will say that the momentum of the particle is related to its associated matter wave and the relation between them is given by:
where \lambda = wavelength of the matter wave associated to the particle, h = planck's constant
and
thus, this highlights the wave nature of the particle and is also relativistic.
Answer:
Explanation:
Since the object is under a circular motion, according to Newton's second law, when the object is at the top of the circle we have:
Where is the centripetal force and is given by:
Replacing and solving for T:
