Question

41. An inventive child named Nick wants to reach an apple in a
tree without climbing the tree. Sitting in a chair connected
to a rope that passes over a frictionless pulley (Fig. P5.41),
Nick pulls on the loose end of the rope with such a force
that the spring scale reads 250 N. Nick's true weight is
320 N, and the chair weighs 160 N. Nick's feet are not touch-
ing the ground. (a) Draw one pair of diagrams showing the
forces for Nick and the chair considered as separate systems
and another diagram for Nick and the chair considered as
one system. (b) Show that the acceleration of the system is
upward and find its magnitude. (c) Find the force Nick
exerts on the chair.

A 3.196E+3-kg Chevy Suburban on route 422 is stopped at the light in Annville heading eastbound. After the light turns green, the driver puts the pedal to the floor. The engine provides a monstrous 1.647E+4 N of forward force on the Suburban. The vehicle passes by the Allen Theatre at 11.3 m/s. Air resistance and friction contribute a 2.544E+3 N force that opposes the motion. Find out how far (in m) the suburban travels in the 3.80 s after it passes the Allen Theatre.

A contestant in a winter games event pushes a 37.0 kg block of ice across a frozen lake as shown in the figure below. The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03. (For each answer, enter a number.) (a) Calculate the minimum force F (in N) he must exert to get the block moving.
The diagram shows overhead views of four situations in which forces act on a block that slides on a frictionless ice surface. In which situations would it be possible for the block to move along the floor with a constant velocity? (Assume the magnitudes of the forces can be adjusted slightly). I do not understand this at all. I know gravitational force is downwards, and frictional force is opposing the pushing force, but how do I solve this?
