[SOLVED] a question
a railcart moves along a railway at constant velocity [tex]v_0[/tex] with a ball attached to its ceiling. at t=0 the ball is drooped from the ceiling and at the same time the railcart breaks are pushed creating deceleration such that its velocity is:
[tex]v=v_0e^{ -pt}\hat{x}[/tex] .
h is the distance between the ceiling and the floor.
in which horizontal distance will the ball hit the floor of the railcart. given [tex]v_0[/tex]=70m/sec
h=180m p=0.0185 1/sec g=10m/sec^2
if you can help me understand this and solve it
thanks
