Question

The momentum of a toy bus of 0.01 kg moving with a velocity of 5 m/s is:
(A) 0.005 kg m/s
(B) 0.05 kg m/s
(C) 0.005 N s
(D) 0.5 kg m/s

Answer 1

Hint
Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion.Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.

Complete step by step answer
We know the mass of the toy bus M = 0.01 kg
The moving velocity of the bus is V = 5 m/s
So, the momentum of the toy is $P = MV$ … which is the formula of the momentum
$\therefore P = 0.01 \times 5 = 0.05kgm/s$.
Option (B) is correct.

Note
Motion is defined as change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation.
