Answer:
0 Nm
Explanation:
Torque is the cross product of the radius vector and the force vector.
τ = r × F
In other words, the magnitude of the torque is equal to the magnitude of the radius times the magnitude of the force times the sine of the angle between them.
τ = rF sin θ
Since F₃ is parallel to the radius vector, θ = 0, so τ = 0.
1m = 1000 mm
0,4m = 0,4 * 1000 = 400mm
Answer:
Since there is no external force, there is no change (movement) in the center of mass. Internally, the center of mass might change position, but the external result is still zero net velocity.
The net recoil velocity must be zero.
