    Acceleration Graph for an Object with Given Force-Time Graph

    well no offense but this guy is a horrible teacher, he made his own book for the class too and its definitely lacking the goods needed to help us figure some of this stuff out. Thanks for the help though, I've been at this stuff all day so my mind is about fried lol, but after i re read what...

    Acceleration Graph for an Object with Given Force-Time Graph

    im not sure, i have a horrible teacher who expects us students to figure this stuff out ourselves so i don't know how a force vs. time graph compares to an acceleration vs. time graph

    What is the acceleration of the upper block connected by a string?

    Homework Statement Two blocks are connected by a string as pictured in this link below http://session.masteringphysics.com/problemAsset/1176902/2/ch05.P070.jpg What is the upper block's acceleration if the coefficient of kinetic friction between the block and the table is 0.11? I am unsure of...

    Acceleration Graph for an Object with Given Force-Time Graph

    Homework Statement A force with x-component F_x acts on a 2 kg object as it moves along the x-axis. A graph of F_x versus t is shown in the figure. Draw an acceleration graph (a_x versus t) for this object. force v.s time graph that was given...

    Force on an Object: Find Force Exerted by 7.0kg Block

    Homework Statement Blocks with masses of 1.0 kg, 7.0 kg, and 9.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 20 N force applied to the 1.0 kg block. A) How much force does the 7.0 kg block exert on the 9.0 kg block? B) How much force does the 7.0 kg...
