_) The magnitude of a force vector F is 82.7 newtons (N). The x component of this vector is directed along the +x axis and has a _) magnitude of 77.5 N. The ycomponent points along the +y axis. (3) Find the angle between F and the +x axis. (b) Find the component > . of F along the +anIS. (a) Number n Units V (b) Number n Units V Multiple-Concept Example 9 reviews the concepts that are important in this problem. A drag racer, starting from rest, speeds up for 449 m with an acceleration of +20.4 m/s2. A parachute then opens, slowing the car down with an acceleration of -6.65 m/sz. How fast is the racer moving 331 m after the parachute opens? Number n Units V A child operating a radio-controlled model car on a dock accidentally steers it off the edge. The car's displacement 0.58 s after leaving the dock has a magnitude of 6.6 m. What is the car's speed at the instant it drives off the edge of the dock? Number n Units v Two objects [50.0 and 17.0 kg) are connected by a massless string that passes over a massless, frictionless pulley. The pulley hangs from the ceiling. Find (a) the acceleration of the objects and (b) the tension in the string. (a) Number n Units v (b) Number n Units V
