2. Luis is trying to make his 65 kg pit bull, named Lazy, go out the back door of his house but the dog refuse to move. If the coefficient of sliding friction between
the sitting dog and the floor is 0.57, how hard must Luis push in order to move
the dog with a constant velocity out the back door?*
Your answer

Describe the path of the electric current through a circuit?

Several mountains together form a mountain . a few of these combined form a mountain system. several systems combined form a mountain , which can stretch thousands of miles in length.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
