Textbook Question
Chapter 4, Problem 5EP
Check with one of your fellow students (or your instructor) to see if the results agree. Notice that there are no other forces acting in the direction of motion (remember, no air resistance). Then, use this force component in Newton’s second law and solve for a. Does your result for the acceleration of the bob (and ultimately its pattern of motion) include the mass?

At southern latitude 1 (refer to Figure 1), under the influence of Corlolz
force, a projectile of mass m is launch vertically upward (along z direction)
with initial speed vo from a point on Earth's surface.

Vo, g, h, properly define constants and coordinates.
Note: neglect air resistance, and consider only small vertical heights, h.

What is the angle θ, in degrees, of the net force, measured from the +x-axis? Enter an angle between -180° and 180°.

A block of mass m is hanging by two strings of negligible mass as shown in the figure.
String 1 is at an angle of 60° with the horizontal and string 2 at an angle of 45° with
respect to the horizontal. Find the magnitude of the force of tension in strings 1 and 2.

A two-inch diameter craft ball is thrown vertically. The initial velocity of the ball is 20 ft/s. Neglecting drag, draw a free body diagram and formulate a first order ODE that governs the velocity of the ball. Is the ODE linear or non-linear? Use Euler’s first order method to determine the “drag free” time required to achieve maximum elevation. Check your solution with the analytic solution to the ODE that governs the motion of the ball. Drag force is known to be proportional to the velocity squared. Draw a free body diagram and formulate a first order ODE that governs the actual velocity of the ball. Is the ODE linear or non-linear? To determine the drag coefficient effect, an experiment has been conducted that showed the terminal velocity of the ball (during a free fall) to be 20 ft/s.
