The ascent of an airplane of mass m may be modeled as three stages. First, the aircraft leaves the ground with a constant acceleration a1 directed upward at an angle θ until time T. Second, the aircraft moves at constant speed until time 6T. Third, the aircraft has a constant downward acceleration until it is moving entirely horizontally at time 10T. Determine the (vertical) lift force on the aircraft as a function of time during the previously described ascent. You should also include a graph of the lift force with respect to t.

1. First, an object 1 with mass m and an object 2 with mass 2 m are moving on a straight line at velocities v1i = 1.00 m / s and v2i = -2.00 m / s. Two objects collided inelastically, and the velocities of object 1 and object 2 changed to v1f and vf2, respectively. The velocity is positive in the right direction, and no external force is acting on these two objects. Find v1f and vf2 for cases...

An airplane propeller is 1.99 m in length (from tip to tip) with mass 93.0 kg and is rotating at 2500 rpm (rev/min) about an axis through its center. You can model the propeller as a slender rod. What is its rotational kinetic energy? Suppose that, due to weight constraints, you had to reduce the propeller's mass to 75.0% of its original mass, but you still needed to keep the same size and kinetic energy. What would its angular speed...

With the use of a phase shift, the position of an object may be modeled as a cosine or sine function (as a function of time). If given the option, which function would you choose (Note: this is an open-ended question; there is no wrong answer; just be sure to explain your choice)? Assuming zero phase shift, if you are using a sine function to model the position of an object, what are the initial conditions of the oscillator---that is,...
