a 25.o kg crate that is initially at rest. note that the view is one looking down on the top of the crate. two forces F1 and F2 act over this crate and it begins to move. the coefficient of the kinetic frictional between the crate and the florr is u=.350. determine the magnitude and direction (...
i have the picture in my book..just tellme if you know how to calculate the inical speed when a body is thrown downward at an angle of 30 degrees (below the horizontal line) with an initial speed of 13m/s?is it the same speed as the inicial vertical velocity or it is only the inicial speed given..?
some body help me...it is very simple...somebody throws two rocks from the top of a hill, one above the horizontal line and the other rock below the horizontal line, at an angle of 30 degrees for both rocks and the inicial speed is 13m/s for both rocks as well...the quiestion is how far does the...
