Answer :
Considering the definition of momentum, the momentum of the curling stone is 57.3 [tex]\frac{kgxm}{s}[/tex].
Definition of linear momentum
The linear momentum or quantity of movement is the magnitude that allows us to measure the capacity of a body in motion to exert a force on another that is in its path.
The linear momentum of a particle of mass m or body m moving with a speed v is defined as the product of the mass times the speed:
P = m×v
Where, as previously stated:
- P is the moment.
- m is the mass of the body.
- v is the speed.
The standard units for moment are [tex]\frac{kgxm}{s}[/tex], and moment is always a vector quantity. Its direction and direction coincide with those of the velocity vector.
Momentum of the curling stone
In this case, you know:
- P= ?
- m= 19.1 kg
- v= 3 [tex]\frac{m}{s}[/tex]
Replacing in the definition of momentum:
P = 19.1 kg ×3 [tex]\frac{m}{s}[/tex]
Solving:
P=57.3 [tex]\frac{kgxm}{s}[/tex]
Finally, the momentum of the curling stone is 57.3 [tex]\frac{kgxm}{s}[/tex].
