Answer:
The speed of the man is 4.54 m/s.
Explanation:
Given that,
Mass of man=8100 g
Mass of stone = 79 g
Speed = 4.5 m/s
We need to calculate the speed of the man
Using momentum of conservation
Where,
=mass of man
=mass of stone
=velocity of man
=velocity of stone
Put the value in the equation
As the stone is away from the man
So, the speed of stone is zero
Hence, The speed of the man is 4.54 m/s.

Answer:
A: In an observer's reference frame, motion lacking uniform velocity includes motion at constant or variable speed in a circle; and motion of a reciprocating device. Supposing the zero refers to the “uniform velocity” rather than the motion removes the possibility of an object at rest.
