Chapter 6, Problem 36P
(III) An inclined plane, fixed to the inside of an elevator, makes a 32° angle with the floor. A mass m slides on the plane without friction. What is its acceleration relative to the plane if the elevator (a) accelerates upward at 0.50 g, (b) accelerates downward at 0.50 g, (c) falls freely, and (d) moves upward at constant speed?

In which of the following situations is there zero net force on the body?
(i) An airplane flying due north at a steady 120 m/s and at a constant altitude; (ii) a car
driving straight up a hill with a 3°slope at a constant 90 km/h; (iii) a hawk circling at a
constant 20 km/h at a constant height of 15 m above an open field; (iv) a box with
slick, frictionless surfaces in the back of a truck as the truck accelerates forward on a
level road at 5 m/s².
(1) A skier of mass m slides up a hill for a distance d along surface coved with snow
till it shops. The motion on the hill is resisted by a force f = pv². Where 0 is the
angle of inclination of the hill. The equation of motion is written as
A block of mass m slides down from rest on a rough incline of
length 8m where the incline makes an angle of 30° with the
horizontal. The block comes to rest on the rough horizontal surface
after sliding for 4 m. The coefficient of kinetic friction on the
incline is 0.30. The coefficient of kinetic friction on the horizontal
surface is different from the incline, find this value using two approaches:
(i) Using Newton's laws of motion and Kinematics and
30⁰
(ii) Using Work-Kinetic Energy Theorem (Give answer to 2 sig. figs.)
