    What is the rate of change of the area of a rectangle?

    Homework Statement Find the rate of change of the area of a rectangle whose area is 75cm^2. The length is 3 times the width. The rate of change of the width is 2cm/second. Homework EquationsThe Attempt at a Solution A=75 A'=? L=3x= 15 L'=6 W=x=5 W'=2 A'=L'W+LW' A'= (6)(5)+ (15)(2) A'=60cm/sec

    Effects of Rolling Resistance on Tension and Acceleration in an Atwood Machine

    There was a track on the table and a cart was placed on it. There was a pulley attached to the cart and hanging at the edge of the table was a "hanging mass". On block A there was rolling resistance/friction between the block and the table as well as Fg and tension from the pulley/string. On...

    Effects of Rolling Resistance on Tension and Acceleration in an Atwood Machine

    We had a lab using an Atwood Machine with block A being on the surface and block B as the hanging object with different masses each round. Rolling resistance was present. Question 1 asked whether or not the tension in the string was less than, greater than or equal to the magnitude of the...
