1. One day in Chapman's class, three students decided to attempt to push a 100kg desk across the classroom. One student pushes with a force of 10N to the right while another student pushes with a force of 23N to the left. The third student pushes with an unknown force. Calculate the magnitude and direction of the third student's force if the desk remains stationary. Calculate the Normal Force.

RESOLVING FORCES
For the following scenarios, be sure to draw a correct Free Body Diagram before solving.
1. One day in Chapman's class, three students decided to attempt to push a 100kg desk across the classroom. One
student pushes with a force of 10N to the right while another student pushes with a force of 23N to the left. The
third student pushes with an unknown force.
Calculate the magnitude and direction of the third student's force if the desk remains stationary.
Calculate the Normal Force.
2.
Three best friends: Mr. Chapman, Detective Manchap, and DJ ChappleJax, were travelling to a Physics
Investigation Festival when their car died. They decided to work together to get this 1200 kg car moving. Mr.
Chapman pushed horizontally behind the car with 40N of force along with Detective Manchap pushing
horizontally with a force of 70N. At the front of the car, DJ ChappleJax tied a rope and pulled the car with a force
of 90N at an angle of 30 degrees above the horizontal.
Calculate the horizontal acceleration of the car.
Calculate the Normal Force.
3. On the way to Petco, Mr. Chapman puts his 20kg dog Khan in a 35kg wagon and rolls him into the store (because
he is a king). Once in the store, Chapman pulls the wagon with a force of 50N at an angle of 70 degrees. If the
wagon begins to move with a constant velocity...
What is the horizontal acceleration of the wagon?
Calculate the Normal Force.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F042b8c16-64f1-4c40-83ed-0ceeda5c118d%2F27feb64c-2d81-468a-8952-ae66ffed949a%2Fk9fp8s7_processed.jpeg&w=3840&q=75)
