Let the magnitude of F2 = 64.0 N and the angle at which F1 pulls be = 65.0°. (a) Find the single force that is equivalent to the two forces shown. The forces are measured in units of newtons (symbolized N).(b) (b) Find the force that a third person would have to exert on the mule to make the resultant force equal to zero.(c) Use I,j notation2 Dimensional MotionWe will consider motion the the x-y plane.Positions now have (x,y) coordinates so we need to use vectors.That’s why we did that pointy stuff on MondayThere are two types of problems we need to considerThrow or drop an object at an angle to the horizontalMake something go around in a circlePositions are VECTOR quantitiesrrrrrrfifiVelocitiesWhich way is the acceleration?Velocity PositionIn 2D motion, lots of things happen at once!An Example …RANGE (R)height (h)What is its velocity here?It’s acceleration?How long did it take to get here?here?Let’s Just Do it!The Monkey Problem – Hit or
