A motorist drives north for 30 min at 85km//h and then stops for 15 min. He continues travelling north and covers 130 km in 2hours. What is his total displacement and average velocity?

A package is at rest on a conveyor belt which is initially at rest. The belt is started and moves to the right for 1.3s with a coonstant acceleration of 2m//s^(2). The belt then moves with a constant deceleration and comes to stop after a total displacement of 2.2m. The coefficient of friction between the package and the belt are mu_(s) =0.35 and mu_(k) = 0.25 . The displacement of the package relative to the belt as the belt comes to stop is 317 xx 10^(-x) The value of x is (g = 10 m//s^(2))
