**Problem Statement:**A 400-N block is dragged along a horizontal surface by an applied force \( \vec{F} \) as shown in the diagram. The coefficient of kinetic friction is \( \mu_k = 0.4 \) and the block moves at constant velocity. The magnitude of \( \vec{F} \) is:A) 100 N B) 150 N C) 200 N D) 290 N E) 400 N **Diagram Explanation:**- The diagram shows a block on a horizontal surface.- An applied force \( \vec{F} \) is acting on the block at an angle.- The force \( \vec{F} \) is decomposed into two components: - The vertical component is \( \frac{3}{5}F \). - The horizontal component is \( \frac{4}{5}F \).**Notes:**- Since the block moves at a constant velocity, the net force on it is zero.- This means the horizontal component of the applied force must balance out the frictional force.

2) An object with a mass of 10 kg is initially at rest at the top of a inclined plane that rises at 30° above the horizontal. At the top, the object is initially 8.0 m from the bottom of the incline, as shown in the figure. When the object is released from this position, it eventually stops at a distanced from the bottom of the inclined plane along a horizontal surface, as shown. The coefficient of kinetic friction between the horizontal surface and the object is 0.20 and between the incline and the block is 0.12. Find the distance d.

One end of a 34-m unstretchable rope is tied to a tree; the other end is tied to a car stuck in the mud. The motorist pulls sideways on the midpoint of the rope, displacing it a distance of 2 m (assume the car slides forward slightly in response to this, but then become stuck again). If he exerts a force of 99 N under these conditions, determine the force exerted on the car. F=F= Incorrect N
