you've saved me for my dynamics exam, thank you so much! ^^

[@roxanashahriari3006]

Very helpful videos! Thank you! why is delta y not Yb-Ya ?

Does the normal force do work?

[@EngineersAcademy2020]

There is no motion in the direction of Normal force, so no work

[@HashemAljifri515]

@@EngineersAcademy2020 I thought there was a work cause there is a normal acceleration:P

at 2.33 why we need to divide the mass 150lb with 32.2

[@EngineersAcademy2020]

150 lbs is weight, so to get mass , m=150/32.2, g value is 32.2 ft/s^2
