Two books are resting side by side, in contact, on a desk. A 0.58 N horizontal force causes the books to move together with an acceleration of 0.21 m/s2 horizontally. The mass of the book to which the force is applied directly is 1.0 kg. Neglecting friction, determine a) the mass of the other books b)the magnitude of the force exerted by one book on the other.

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
