**12. A 1200-kg car is being driven up a 5.0° hill. The frictional force is directed opposite to the motion of the car and has a magnitude of f = 524 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 Fy directed perpendicular to the road surface. The length of the road up the hill is 290 m. What should be the magnitude of F, so that the net work done by all the forces acting on the car is +150 kJ?

You are trying to slide a heavy trunk across a horizontal floor. The mass of the trunk is 85kg, and you need to exert a force of 3.3*10^2 N to make it just begin to move. a)Determine the coefficient of static friction between the floor and the trunk.b)After the trunk starts moving, you continue to push with this force. The trunk reaches a speed of 2.0m/s after 5.0s. Calculate the acceleration of the trunk if the coefficient of kinetic friction between the trunk and the floor is 0.32.

The figure shows a block of mass m resting on a 20o slope. The block has coefficients of friction us=0.64 and uk=0.54 with the surface of the slope. It is connected using a very light string over an ideal pulley to a hanging block of mass 2.0 kg. The string above the slope pulls parallel to the surface. What is the minimum mass m so the system will remain at rest when it is released from rest?
A block with mass m = 5.35 kg is sent up a ramp with an angle of 35.0◦ in relation to the horizontal as shown in the figure above.
