A person is trying to move a block of wood by pulling on it with a rope. The rope makes an angle of 15° with the ground. The mass of the wooden block is 100 kg, and the coefficient of static friction between the block and the ground is 0.1
- Draw the free body diagram of the wooden block
- If the wooden block is not moving yet, write the equation describing how the forces are related in the horizontal dimension.
- Write down the equation describing how the forces are related in the vertical dimension.
- What is the normal reaction force R exerted by the ground on the block?
- How much force does the person has to pull with to get the block moving?
