A block of mass m = 7.19kg is free to move along the x-axis of a rough horizontal surface. The mass is subject to the force of gravity, a normal force, a force of kinetic friction, and a position-dependent force. The coefficient of kinetic friction is μ = 0.363. The position-dependent force is given by F(x) = (22.05x – 9.34x²)î. When the block is at ri 1.02mi it moves with velocity v₁ = 8.17. (The input below will accept answers with no more than 1% variation from the correct value.) What is the kinetic energy of the block when it is at 7₂ J = = 1.02mi?

A 1510-kg car is being driven up a 7.00 ° hill. The frictional force is directed opposite to the motion of the car and has a magnitude of 487 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 287 m. What should be the magnitude of F, so that the net work done by all the forces acting on the car is 213 kJ? Number Units
An object with mass m = 34 kg is pushed with 452 N of force to be moved across a distance of 4.6 m on a surface with friction. Initially the object is moving at vi = 0.82 m/s and after being moved across 4.6 m, the final speed is 2.5 m/s. What is the magnitude of the frictional force acting on the object in the unit of N
A rectangular block has a length that is six times its width and a height that is three times its width. The block's surfaces are all identical except for size. When the block is placed on a horizontal tabletop so that the area in contact with the table is length ✕ width, it is found that a horizontal force of 11.6 N applied to the block is just sufficient to overcome the static friction force and cause the block to move. The block is then knocked over so that the area in contact with the table is length ✕ height. Now, what minimum horizontal force will cause the block to move?

A block is set into motion up an inclined plane (30° ) with an initial speed of 8.0 m/s. There is friction between the block ant the plane. The block comes to rest after traveling 4.8 m along the plane. V =8 m/s What is the value of the coefficient of friction u? HINT: remember that the friction force is given by f = µN = µ = N thus because both f and the N are proportional to the mass of the block m, m cancels out and you don't need it to find u. Thus you wont be able to find a value for f or N alone, so find your acceleration first, then an equation for u that is independent of m.
