To understand why a horse has to apply more force to start a cart than to keep it moving, we can break down the explanation into several steps: ### Step 1: Understanding Friction Types Friction is the force that opposes the relative motion of two surfaces in contact. There are two main types of friction: - **Static Friction (Fs)**: This is the friction that acts on an object at rest. It must be overcome to start moving the object. - **Kinetic Friction (Fk)**: This is the friction that acts on an object that is already in motion. ### Step 2: Comparing Static and Kinetic Friction ...

A block of mass 10 kg is kept over a rough surface and a force F=4t is applied on it. At what value of t the block will start moving :-

A 20 kg block is initially at rest. A 75 N force is required to set the block in motion. After the motion a force of 60 N is applied to keep the block moving with constant speed. The coefficient of static friction is
