What fields are especially important?

Classical Mechanics 0
A particle moves in a circle (center O and radius R) with constant angular velocity \(\omega\) counter-clockwise. The circle lies in the xy plane and the particle is on the x axis at time t = 0. Show that the particle's position is given by \(\mathrm{r}(t)=\hat{\mathrm{x}} R

Consider the projectile of Section 2.3. (a) Assuming there is no air resistance, write down the position (x, y) as a function of t, and eliminate t to give the trajectory y as a function of x. (b) The correct trajectory, including a linear drag force, is given by (2.37). Show that this reduces to you

Consider a grey squirrel falling out of a tree to the ground. (a) If we ignore air resistance in this case (only for the sake of this problem), determine a squirrel's velocity just before hitting the ground, assuming it fell from a height of 3.0 m. (b) If the squirrel stops in a distance of 2.0 cm th

When tetrapods first ventured onto the land, what new selection pressures did they face? What characteristics might have fostered the success of these animals as they made the transition from aquatic to terrestrial habitats?

A college student has two options for meals: eating at the dining hall for $6 per meal, or eating a Cup O Soup for $1.50 per meal. Her weekly food budget is $60. a. Draw the budget constraint showing the trade- off between dining hall meals and Cups O Soup. Assuming that she spends equal amounts on b
