A worker on a railway cart is pushing a box. The cart is moving at a constant speed of 20 m/s by some external agent. The box has a mass of 25 kg, and is being pushed forward over a distance of 2m on the cart by the worker at constant acceleration, increasing its speed from 0 to 2 m/s relative to car.
(b) How does Girish standing on the ground interpret a similar measurement?

AI Generated Solution

To solve the problem, we need to analyze the situation from both the perspective of the worker on the cart and Girish, who is standing on the ground. ### Step-by-step Solution: 1. **Identify the Given Information:** - Mass of the box (m) = 25 kg - Initial speed of the cart (v_cart) = 20 m/s - Initial speed of the box relative to the cart (u_box) = 0 m/s ...
