In a tug of war, the team that exerts a larger tangential foce on the ground wins. Consider the period in which a team is dragging the opposite team by applying a larger tangential force on the ground. Which of the following works are negative ?

work by the loosing team on the winning team

work by the ground on the winning team

work by the ground on the loosing team

none of these

Text Solution

Verified by Experts

The correct Answer is:

Displacement of the winning team is zero. Hence work done by loosing team on the winning team is zero.
Ground applies a frictional force on the losing team in a direction opposite to its displacement hence work done by ground on losing team is zero.

Two blocks are in contact on a frictionless table. A horizontal force is applied to the larger block, as shown in Fig. 5-53. (a) If m_(1)=2.3" kg", m_(2)=1.2" kg", and F = 3.2 N, find the magnitude of the force between the two blocks. (b) Show that if a force of the same magnitude F is applied to the smaller block but in the opposite direction, the magnitude of the force between the blocks is 2.1 N, which is not the same value calculated in (a). (c) Explain the difference.
