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

You are a member of an alpine rescue team and must get a box of supplies, with mass 2.10 kg, up an incline of constant slope angle 30.0° so that it reaches a stranded skier who is a vertical distance 2.90 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10-2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.81 m/s². Part A Use the work-energy theorem to calculate the minimum speed that you must give the box at the bottom of the incline so that it will reach the Express your answer numerically, in meters per second. ► View Available Hint(s) V= ΕΠΙΑΣΦΑ A20 ^ ? m/s
