The conveyor belt delivers each 12kg crate to the fixed ramp atpoint A such that each crates velocity is 2.5 m/s as it starts toslide down the ramp.If thecoefficient of kinetic frictionbetween each crate and the ramp is u_{k}=0.3, complete thefollowing.
Develop the impulse momentum equations for the crate as it slidesdown the inclined ramp from point A to point B in the figurebelow.
Using impulse momentum equations, derive an expression than can beused to determine the velocity of the crate for any time t as thecrate slides down the ramp.What is the velocity of the crateas it slides off the ramp at point B.
And lastly using the conservation of energy relationship,V_{1}+T_{1}+W_{NC}=V_{2}+T_{2},verify that the velocity determined inthe previous step iscorrect. assume positions given in diagram
