Homework Statement So its log(base2)(1-2x) Homework Equations The Attempt at a Solution I understand that derivative of log(base:a)x equals 1/xlna. However, using (1-2x) for x and 2 for a I got 1/(1-2x)ln2. Of course, i have to use the chain rule, which turns out to be -2. So my...

So, by using the theta and the given vertical component, I was able to find the total distance. Then, using the initial PE and final KE, I found the difference in energy lost and therefore work done by the air, setting up the equation W=fd I got f(air resistance)=-1897.8N. Does that sound right...

Homework Statement Early test flights for the space shuttle used as a glider (mass of 980kg). After a horizontal launch at 480 km/h at a height of 3500m, the glider eventually landed at a speed of 210 km/h. What would its landing speed have been in the absence of air resistance? also, what was...

Homework Statement A skier of mass m starts from rest at the top of a solid sphere of radius r and slides down its frictionless surface. At what angle (theta) will the skier leave the sphere? And if friction were present, would the skier fly off at a greater or lesser angle? Homework...

Yes, they are both variables.

Homework Statement It is simple: find the antiderivative of 2xy. Homework Equations The Attempt at a Solution I am inclined to say that it equals (xy)^2 +c, but can't help but feel i have left out something.
