A stone of mass 1 kg is thrown with a velocity of `20ms^(-1)` across the frozen surface of a lake and it comes to rest after travelling a distance of 50m. What is the magnitude of the force opposing the motion of the stone?

Text Solution

AI Generated Solution

To solve the problem step by step, we will use the equations of motion and Newton's second law of motion. ### Step 1: Identify the given values - Mass of the stone, \( m = 1 \, \text{kg} \) - Initial velocity, \( u = 20 \, \text{m/s} \) - Final velocity, \( v = 0 \, \text{m/s} \) (since the stone comes to rest) - Distance traveled, \( s = 50 \, \text{m} \) ...
