c) increase, decrease
because, the resistance of air increases as the speed of the skier increases.
so, his acceleration decreases gradually from g(9.8 m/s^2) to 0.
then the skier falls with a constant speed which is called as terminal speed.
so, before getting terminal speed his speed gradually increases and acceleration decreases.

Minds on Physics Internet Modules For Stu Tea Newton's Laws NLS F=ma Calculations Consider the free-body diagram shown below. Use the numerical value for the individual forces and the approximate value of g (10 m/s/s) to determine the acceleration of the object (in units of m/s/s). Assign a negative number to the acceleration if it is leftward or downward. Enter a numerical answer. ####! Fnorm = 40 N Ffrict = 15 N Fapp = 35 N Fgray = 40 N

Newton's Satellite Directions: Read the background information and complete the activity Newton's Thought Experiment In the seventeenth century, Sir Isaac Newton was studying the nature of motion and gravity. He formulated a thought experiment that would eventually become the basis of the development of satellites. Imagine an object is fired from a cannon horizontal to the plane of the earth. The projectile will travel in a horizontal direction and undergo projectile motion as gravity begins to pull the projectile downward....
