AI Generated Solution

To determine whether the person holding a suitcase while moving on a horizontal platform is doing any work, we can analyze the situation step by step. ### Step-by-Step Solution: 1. **Understanding Work Done**: Work done (W) is defined as the product of the force applied (F) and the displacement (d) in the direction of the force. Mathematically, it can be expressed as: \[ W = F \cdot d \cdot \cos(\theta) ...

A coolie carrying a load on his head and moving on a frictionless horizontal platform does no work. Explain the reason why.

Two persons, A of mass 60 kg and B of mass 40 kg , are standing on a horizontal platform of mass 50 kg . The platform is supported on wheels on a horizontal frictionless surface and is initially at rest. Consider the following situations. (i) Both A and B jump from the platform simultaneously and in the same horizontal direction. (ii) A jumps first in a horizontal direction and after a few seconds B also jumps in the same direction. In both the situations above, just after the jump, the person ( A or B ) moves away from the platform with a speed of 3 m//s relative to the platform and along the horizontal. In situation (i), just after both A and B jump from the platform, velocity of centre of mass of the system ( A, B and the platform) is

Two blocks of masses m_(1) and m_(2) are placed in contact with each other on a horizontal platform as shown in figure The coefficent of friction between m_(1) and platform is 2mu and that between block m_(2) and platform is mu .The platform moves with an acceleration a . The normal reation between the blocks is

A body of mass M is kept on a rough horizontal surface (friction coefficient =μ). A person is trying to pull the body by applying a horizontal force but the body is not moving. The force by the horizontal surface on the surface of the body is F, where

A person pushes a box on a rough horizontal plateform surface.He applies a force of 200 N over a distance of 15 m. Therefore, he gets progressively tired and his applied force reduces linearly with distance to 100 N. The total distance through which the box has been moved is 30 m. What is the work done by the person during the total movement of the box?

A fat person is standing on light plank floating on a calm lake. The person walks from one end to the other on the plank. His friend sitting on the shore watches him and finds that the person hardly moves any distance because the plank moves basckward about the same distance as the person moves on the plank. Explain.
