Forces of Friction; Free Body Diagram Tutorial; Assignment: Online homework 26 Quiz 26 (due April 23rd) class notes. recording. Outline. Week 27. April 14th. Topics: ... Kinetic Energy and the Work-Kinetic Energy Theorem; Friction is divided into two types-static and kinetic. These are represented by Ff, with a further subscript ' ... Answer: Unknown initial speed u. Unknown net acceleration a. The kinematics equation for velocity accelerated from u to v over displacement s v^2 = u^2 + 2as We are told that v = u +4 m/s, and s = 5 m, so (u+4)^2 = u^2 + 2a*5 u^2 +8u +16 = u^2 +10a a = 0.8u +1.6 ———————— [1] Applied motiv...
