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. F₁ = 40 m = 1200kg F₂ = 76 F3-30 Calculate the horizontal acceleration of the car. Calculate the Normal Force. N
