Question
Draw the following graphs for an object projected upward with a velocity $v _0$, which comes back to the same point after some time:
i. Acceleration versus time graph,
ii. Speed versus time graph,
iii. Velocity versus time graph.
i. Acceleration versus time graph,
ii. Speed versus time graph,
iii. Velocity versus time graph.
[Note: The simple result of this exercise was one among the several arguments advanced by W. Pauli to predict the existence of a third particle in the decay products of β-decay. This particle is known as neutrino. We now know that it is a particle of intrinsic spin ½ (like $e^-$, p or n), but is neutral, and either massless or having an extremely small mass (compared to the mass of electron) and which interacts very weakly with matter. The correct decay process of neutron is: n → p + $e^-$ + v]
