If fast Freddy doubles his running speed, what else doubles?
(a) His momentum (b) His inertia
(c) His time of running (d) His acceleration
The correct option for the statement “If fast Freddy doubles his running speed, what else doubles”.
Answer to Problem 1RAT
The option (a) is correct for the statement “If fast Freddy doubles his running speed, what else doubles”.
Explanation of Solution
The momentum of an object depends only on the mass and speed of the object. It varies according to the variation in mass and speed of the object.
If the running speed of Freddy becomes double then the momentum of Freddy also doubles because the mass of Freddy remains same.
The inertia does not depend on the running speed, so the inertia of Freddy remains same.
The time of running does not affect the momentum of Freddy.
The acceleration is the physical quantity which is rate of change in speed with time. The rate of change of speed remains constant, so the acceleration of Freddy does not change due to doubling the speed.
Conclusion:
Therefore, option (a) is correct for the statement “If fast Freddy doubles his running speed, what else doubles”.
