What is the x component of the resultant force? Express your answer in newtons. • View Available Hint(s) Two forces, F1 and F2, act at a point. Fi has a magnitude of 8.00 N and is directed at an angle of 63.0 ° above the negative x axis in the second quadrant. F2 has a magnitude of 6.00 N and is directed at an angle of 53.3° below the negative x axis in the third quadrant.

A 5 kg block is attached to a spring of constant k = 2400 N/m. The coefficient of friction between the block and the ground is 0.4. Under its initial condition, a force F is applied to the block until the restoring force of the spring reaches 100 N. To reach its final condition, the applied force F is removed. Then, the block moves and the spring returns to its unstretched position. Use 9.81m/s^2 for the gravity. a) Using the formula Fspring=kx, determine the distance in meters of the block from its unstretched position until it has a restoring force of 100N. b)Determine the work done by friction in Joules from the initial position (stretched) to its final position (unstretched). c)If the total work done on the system is 1.2658 J, determine the final velocity of the block (by relating work and kinetic energy)

A 1470-kg car is being driven up a 5.76 ° hill. The frictional force is directed opposite to the motion of the car and has a magnitude of 515 N. A force F is applied to the car by the road and propels the car forward. In addition to these two forces, two other forces act on the car: its weight W and the normal force FN directed perpendicular to the road surface. The length of the road up the hill is 289 m. What should be the magnitude of F, so that the net work done by all the forces acting on the car is 192 kJ?

A block of mass mA = 20kg on an inclined plane and a bucket of mass mbucket = 14kg are attached to the ends of a massless string passing through a massless pulley as shown in the figure below. The inclined plane makes an angle of 0 = 37° with the horizontal and the coefficients of kinetic and static friction are μ = 0.2 and μ = 0.5. The system is initially at rest and a student starts to fill the bucket with balls, each of whose mass is 100 grams, one at a time until the system starts to move. Determine the number of balls the student placed in the bucket. Take g = 9.80m/s² and please note that the number balls must be an integer! Answer: MA mbucket
