A575 g squirrel with a frontal surface area of 0.0146 m^2 falls from a 8.5 m tree to the ground. assume the density of air in this problem is given by 1.21 kg/m^3. (a) what is its terminal velocity in m/s? (use a drag coefficient of 0.70 and assume down is positive) (b) what will the velocity (in m/s) of a 56 kg person falling that distance, assuming no drag contribution?

Find the dimensions and area of the largest rectangle that can be inscribed in the upper half of the ellipse. (give your answers in terms of a and b. enter the dimensions as a comma-separated list.)

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
