Consider an object in free fall starting at position x_i=y_i=0 and ending up at some arbitrary final point (x_f,y_f). The initial velocity is v_i->=(v_x, v_yf)- note that the x-component of velocity is constant because we are in freefall. a)draw the free body diagram for the object. c) show that the work done by gravity is going from (0,0) to (x_f,y_f) is W=-mg delta y=-mgy_f. c)show that the change in kinetic energy is deltaK = 1/2 m(v_yi^2- v_yt^2). d)use the work-energy theorem to prove that delta(v_y^2) = -2gDeltay.

QUIZ: Free fall and air drag Due Menday-Tuesday no exceptions Two objects are dropped simultaneously from an initial height of 100m, with an initial velocity of zero. They fall straight down. For mass 1, you can ignore air drag. For mass 2, air drag DOES affect the motion. Here is the position vs. time for both objects: 100 90 80 %, y-100-0.1164*t-4.795%40.1283*t3 70 60 mass 1: no air drag n mass 2: with air drag 50 40 30 y 100-1/2...

1- A 300 ? mass is attached to
a solid 40 ?? long string the other end of which is secured to the
ceiling. The mass is given an initial speed which makes it swing
around a circular path in the horizontal plane without changing its
speed and without changing its height. The object completes 2
revolutions in 2 seconds.
A) What is the magnitude of the angular velocity of this
circular motion? B) Find the tension in the string....
