Hello, I am a junior in High School and some of my friends in my physics class and I have a study group for our weekly bookwork that our teacher assigns. We have tried all week to figure out this one problem but to no avail. The problem is as follows: Two forces are applied to a car in an effort to move it. A)What is the resultant of these two forces? B) If the car has a mass of 3000 Kg, what acceleration does it have? the diagram of the car shows that it is being pulled in two different directions one arrow is pointing northeast with a force of 400 Newtons at an angle of 30 degrees, and the other direction is northwest at an angle of 10 degrees and a force of 450 Newtons. I tried using 400cos30 and 450cos10, but it doesn't work. The answers are in the back of the book, but I'm looking for how to do the math and I don't want to just copy the answers down because I would like to know how to solve this. If it helps, the answers are: A) 789 Newtons at 8.8 degrees to the right of forward direction B) 0.266 m/s^2 in direcrion of resultant force Thank you in advance, and please help me with the math in this problem.
