you hav to do it yourself but what is contact force here is the answer
A Contact force, is a force that acts at the point of contact between two objects, in contrast to body forces. Contact forces are described by Newton's laws of motion, as with all other forces in dynamics.
Contact force is any force that requires contact to be enforced. Contact forces are also direct forces. Contact forces are ubiquitous (present, appearing, or found everywhere) and are responsible for most visible interactions between macroscopic (visible to the naked eye; not microscopic) collections of matter. Pushing a car up a hill or kicking a ball or pushing a desk across a room are some of the everyday examples where contact forces are at work. In the first case the force is continuously applied by the person on the car, while in the second case the force is delivered in a short impulse. Certain contact forces describe specific phenomena and are important enough to have been given unique names. The most common instances of this include friction, normal force, and tension. According to forces, contact force may also be described as the push experienced when two objects are pressed together.
