A 2.0-N force is applied to a 1.0 kg book in order to move it across a desk with an acceleration of 0.5 m/s2. Determine the Frictional Force acting on the book.

In a system, when potential energy decreases, then entropy also decreases. true false

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
